My custom built .50 BMG
 

Here is my interpretation of the .50 BMG (Blasty Machine gun)

It was hand crafted in my garage over this winter using the most basic of tools.

Jigsaw,Hacksaw,skill saw with abrasive blade and my trusty drill.

Its full metal and fully functional.

Features
-Metal construction,very solid and hefty
-v6 gearbox for high relibility
-750 round BB capacity
-Working Charging handle to ready the gun to fire
-adjustable tripod
-420 FPS

Gun is approximately 98% complete. I have to finish up the sights and a better latch for the feed cover.

Had it out to our Vietnam game and it was quite the hit.

Anyhow here are some pics if anybody is interested.

Probably put a video up sometime if anybody wants.

Wow! That is frigging amazing, and you said you built it yourself? You making some more or what? :razz:

Awsome work, that is really damn awsome.

thats pretty nuts, would be fun to be controlling that thing while flying around on the boat.

and a video would be nice to see =)

Yeah awesome work :) pretty nice looking hmg!

Absolutly amazing man. Keep up the good stuff... maybe work on some other .50 cal weaponry... WINKWINK.50anti-material sniperWINKWINK


Always good to see the crafty ones putting their skills to work

Why am I NOT surprised, John, coming from you of all people............ the guy who brought us mortars and shoulder fired NERF guns!!!

VERY nice job!!!!!!!!! Need to make us one for the Warmonger SCAT2 hovercraft! ;)

Damn ya beat me to it :P

Ontario players, keep an eye out for my 50 comming to a tehcnical near you!

craaaaaaazy... amazing job...

Very nice! what type of gearbox did you use? How does it feed?

Wow good job, looks great!

Version 6, same in the P90.

Am curious myself! :D

wow.
I wish I had one.
I'm a machine gun freak
Greg

It feeds pretty good. Sometimes I am lucky and can fire off all 750 with no misfires. :-)

I will get a video soon.

It's every bit as impressive as a minigun.

would there be any way to do the same setup, except put multiple systems into the same unit. explaining that a little better, if you mounted 2-3 mechboxes/internal units into the main box, hook it up to a single firing mechnism/trigger you could probably fit the corresponding tightbores into the .50 barrel which would give an insane rof. thoughts?

Mikeman that was my initial thoughts too. But as I got to work on it I found it impossible to fit 2 gearboxes in and make them shoot out of the barrel and still be able to maintain the dimensions and features I wanted.

But as an aside I do have plans for a 8mm gas version.

btw real m2 has a slow rate of fire anyhow. I am already probably shooting two or 3 times faster then it.

But it is airsoft and in real life the .50 would kick some ass while in airsoft 6mm is 6mm is 6mm.

I am in love :tup:

Nice work BM! Using basic tools requires a lot of patience. I think you could worry your way out of prison if you had an unlimited supply of plastic spoons.

I bought an electropneumatic pball gun a few years ago with the intention of a very noisy airsoft project. The gun has changable fire modes: semi, 3rnd burst, 6rnd burst, f/a. Stripped down, the important stuff is pretty small: about 2.5" tall, 8" long, 1.25" wide. The gas pressure applied to the pneumatics operating system and the breech are separately regulated so it's possible to modulate muzzle velocity without affecting the recoil cycle (i.e. it can be downtuned to safe muzzle fps without sacrificing recoil perf'). ROF is electronically controlled and is quite easy to adjust (turn a pot').

At FA, this thing is a loud monster.

I think you could hide a decent sized CO2 bottle in a belt bag or even within your rec'r itself. The strong pneumatics could also cycle a bolt plate for more metal clinking fun.

Pretty cheap too at $300 (used) including regulator on a Canadian pball forum. If I had the time, I'd put it into a MG, but I'm not sure if I'd ever get around to it.

Very nice, imagine the mayhem that could be had if you and Zero Delay ever collaborated...

Wow !! it's a big toy for a big boy :lol:

amazing, you are definitely a genius!!!

http://www.marstar.ca/semi-mg/live-1919A4.htm


Wouldn't you want a REAL one instead? ;)

very very nice

Mass produce! (Yeah yeah making a single one was already an endeavour itself)

Edit: Yeah how does that monster feed anyways?

Edit Edit: Gravity Fed?

Nope its electric feed. servo on m16 highcap. Gravity won't keep up. I did mess around with gravity feed for fun but its not reliable that way.

I will take some pics of the internal stuff sometime soon.

woow requires a PAL only.

The link is to a 1919 not a m2. Though they have a semi version also it is sold out and if it wasn't sold out it costs 10g.

I think its a bit silly to say wouldn't you want a real one. Ofcourse we are airsofters but thats why we play airsoft to use guns to shoot our buddies we could never get in real life like a Full Auto m2. Semi would be cool too but sheesh not worth it in my opinion.

man u r like a god.

thats not a .50 cal........;)

I had a chance to try this, and it actually shoots better than most people's aegs: fast, hard, and straight. Truly awesome, and as I said at the time- the most impressive thing I've ever seen built in the name of airsoft.

So THIS is what my P90 became! Awesome!

Very very impressive... but who's taking a pee in the pond?

Lin who else? lol

you are a Mechanical God!! Good shit man lol

How well does it shoot?

Nic

:salute: WOW :salute:, do you have anymore vids of that beauty from different angles, or from games?

WOW :shock:
 

:shock: thats awsome man! but did u build the whole thing from scratch? cuz thats really impressive! and if u did how did u make the bipod for it?.. still in shock! your truly an artist that thing should be in the airsoft museum and if there isnt one there should be one just for u :tup:

Its not a bipod its a tripod. I made it with pipe and welding it.

Why am I not surprised??

Well I guess that ruins my whole idea for doing the frog-man idea at the next big game with you boys.

haha Well I am still going to brave it. Maybe in my NBC suit!

For being a Frogman we need to buy those Sea-doo Water scooters from Crapadian Tire. They do 3.2kph and last about 1.5 hour run time. slap a coat of OD or black on them to make em tactical.

Johnny's a god- was at that 'Nam game watching Wolfman shoot at the tops of the cat tails or bullrushes (whatever the F*ck they are called) and hitting them consistantly. Put my AEG to shame:( The uber AEG, keep telling him to draw up plans or make me one! lol. Who wouldnt pay 500.00 or more for that?

His nerf launcher is something top behold as well...

Well considering it pretty much costs 500 to get the gearbox ( buying a p90) and all the other materials and time if I was to sell ya one it would definately be alot more. :-)

Great job, looks very nice.

Awsome work! Post up some pics of the internals. I got a version 2 mechbox that only works in full auto kicking around here, I was going to part it out, but now you're giving me ideas lol

a version 6 is needed for this project because of it's basic (rectangular) shape and the location of the motor and feed nozzle. A version 2 would be very hard to make work in this gun.

yeah, probably not going to do it anyway, cos I need the cash the parts can generate lol

but I was thinking of making an airsoft Browning 30 cal.

Well if you give a price on the thing..hmmm..*counting on fingers and toes* maybe I could get some the dragons..hmmmm...


DAMN!!! THATS A NICE FREAKIN GUN!
:D

:o :o :o :o :tup: :tup: :tup:

This is ABsolutely one of the kind! Unique and excellent craftmanship

:cheers: :cheers: :cheers:

I know what it would have taken to make that John and I think you did a awesome job to say the least. I wish I could see the feed tray better because I bet it was one of the biggest challanges in the project, that along side the numerous rivets you had to replicate. The charging handle is intriguing, does it act as a safety, ensuring the system is only energized when it is in the rearward position, or does it perform another mechanical function?

The charging handle is functional. When you open the feed tray to load more bb's in, you must close the tray, then pull the charging handle to activate the trigger like you would on the real .50.

Yeah ERT got it right. After you open up the feedtray and load the gun you must pull back the charging handle before the gun will be able to fire.

I also have a safety by the trigger. I will try to get better pics of the inside and other things soon.

I figured that the charging handle may have actually acted as a sort of switch for the electrical system, when it is in the cocked position the terminals are in contact, charging the mechbox with power but I guess I was mistaken.


I had been doing some basic design work on one of these for that DPV awhile ago, as the SEALs commonly armed them with the Ma duece, as well as the Honeywells and the TOWs, but I sort of wanted some sort of Anti-tank type capability that could be fired from the cockpit (when the TOW is secured to the transport cradle, and aimed directly forward) or from the Gunner gage at any opposing vehicles, so I never really took it past the design stage. Because I spent a considerable amount of time assesing what it would take to replicate one I know the design characteristics very well, and you have recreated it very close to the actual unit.

One other question I was wondering about, was whether you had considered a PCG gearbox? A teammate of mine installed one into a M249, I was present for the majority of the installation and at that point I realized that it would make a excellent basis for the internals of one of these slab sided Browning MGs, since it too is rectangular and has a horizontal mounted motor. I was conceptualizing it as using a .50cal ammo can to house both the feed servos and the ammo storage, but that is on a vehicular platform in which weight and portability aren't a factor, as they would be if it was used in the role as a Crew served support weapon by infantry.


Too bad all these stunning game enhancement props are being metiulously crafted, and for what ever reasons there isn't the huge venues this season needed to deploy them in the roles they would be most suited for. It's kinda driving me into despair:sad:

Well you are correct it there is an electrical switch involved. But you pull the Charging handle back and release it to activate.

I have thought about the PGC. The cost was a factor and availibity too. Though it might of been a better choice as even the v6 was tough to squeeze in and align the barrel. I know the size of the m2 reciever is deceptively big thinking it would be easy but the fact is the barrel comes out of the bottom and its not easy to line up the the nozzle too.

There was the option of inverting a mecbox though. I could of done that. But I was able to get a v6 box done up and it worked being upright so I went ahead that that.

And yes I am also disspointed in not being able to employ any special weapons. Its a bit discouraging to put so much time and effort into building rocket launchers, special guns,Mortars and other things and then not have game turnouts or events planned to warrant the use.

But so far its not going to stop me. I am going to keep trying to come up with Milsim creations.

"If you build it they will come." springs to my mind. I hope so.

Lol, it's a compulsion, like painting or sculpting, if you are deprived of the ability to excersize the urge to tinker with stuff you end up saddled with anexiety, thats the way it is with me anyway. My brain doesn't like to sit idle it has to be worked to exhaustion before it will rest lol.

I thought the alignment of the barrel would prove problematic, the exploded schematics i had seen of the real M2s indicated that it loads rounds closer to the bottom of the reciever unlike small arms weapons typically do, and I suspected that would create some spacing issues that would have to be rectified, seen as most gearboxes are designed to replicate weapons that load rounds the opposite way that M2s do. You overcame those problems though, and that's cool. You probalby did the best thing keeping the mechbox upright, inverting it may have led to you having to flip the feeding mechanisms also, and that may or may not have caused other problems.

I always loved .50cals they are like the Grizzly bear of the U.S arsenal. Big. slow moving and mindbendingly powerful. Hopefully I can get all the crap I'm working on now completed in time to start on some. I'd like to use one of them as a alternative weapon for that DPV when the TOW isn't necessary, and if i have to go thru the trouble of fabricating one I' may as well make two or three concurrently, seems like I can't just make one of anything anymore, it's alot different for me now as i see things from a differnt perspective when building weapons as a game organizer as opposed to a player.I'm not concerned with attaining an advantage over other players only with trying to maintain ballance among the teams. Kinda like parents who can't buy Billy a new bike with out getting his brother one too lol.

It would be cool if we ever shared the field again to have M2s equipped on both sides as peremiter defence weapons. It would mean choosing the avenue of aproach to the target a lot more carefully with the knowledge that there is .50s deployed out there. If you make a 8mm unit that will mean there will be multiple units, enough that they could actually be a effective deterent to any raid attempts by both sides on any real estate they are set up on. Another leap forward in achieving a more realistic game environment.

I'm of the same mindset, every new thing I come up with is done with the hope of creating a more immersive experiance, one that doesn't rely soley on "Suspension of disbelief" to keep the andrenaline and excitment level elevated. With out these types of "Force multiplier" weapons and the interactive props the game runs the risk of stagnating and losing experianced players that it needs to retain to continue to evolve. With out that experianced element the game can never really expand much beyond the basic "Run 'n Gun" stage that it started out as. If it doesn't grow with the players then it ends up becoming something that people lose interest in. There has to be more to the game than the simple "shoot each other" aspect. To facilitate that growth there has to be some kind of added complexity to the objectives of the game, and nothing can do that as well as well thought out weapons and interactive props IMO.

That thing looks sweet. I REALLY gotta see this thing!

cheers :cheers:

Amazing work :)

need help
 

Im also trying to build an m2bmg, it would be a big help if U could contact me.
I need some plans and instructions, that would help a lot.

My god. I have a rice pudding ozzing out from looking at this. Great job !

geez that looks awesome. thats really going to turn heads in some other countries =)

great job

Any plans on posting up some pictures still. Ive been seriously planing to build a 1919a4. Id love to see some picture of the internals. Im still figuring out the best way to attach the barrel to the receiver. Secure the hop up and mechbox. Maybe seeing what you did will give me some new ideas.


Thanks

Id love to see someone in Canada market this product.

The BMG has been a great addition to our games. It's a wonderful unit to have available.

One night game we outfitted the lone machinegunner on the .50 with a pair of NVGs. The rest of the team had to locate his position and take him out. We spent most of the time crawling up while listening to the .50 firing and BBs whizzing through the grass. I caught one on the top of the head, but most of the others made it up. The .50 ran dry and it came down to the sidearm...

The last game we had one team mined an objective area (with some CO2 mines we had) and also planted the .50 in a concealed spot with a good field of fire. The other team knew the place was mined but had no idea they were walking into the .50's maw. Actually, the .50 didn't fire - there was a malfunction of some kind. The gunner spent his time pressing the inert trigger and pulling the charging handle instead of shooting until he got shot. Much funnier that way anyway.

More attendance! http://www.airsoftcanada.com/images/...on_redface.gif

But I'm with Blastyman... "if you build it, they will come".

friggen mines.. they scare the bejeepers out of ya when ya set one off.. damn it. :lol: once that 50 came alive it kept the advance at a stall, didnt hit us but we had spoons trying to dig into the ground just a little further.. talk about effective.

Nope, Unfortunately I didn't make that one.

wahts this about a nerf rocket launcher. tried doing a search only tocome up empty handed.

Yah you would think the HMG would go for more then the price of the gearbox. probably the reason why most HMG is over the 1'000 range.

Man a 50 cal would be awesome for a WWII game.

unfortunately, the EAR site was down and i think they lost the pics and video of the mortars, bazooka, etc. take it from me firsthand there is nothing like hearing a "WHOOMPF" is the distance, then a few seconds later the classic movie whistle of an incomming mortar, then a thud near you. and this could happen 20 times in a couple of minutes like when we were bombared at the "Robin Sage" event in august. blastyman is the "evil genius" of the airsoft world. maybe if donp still has the near suicidal vid of john's attack with his new launcher he could link it.

I am so glad I realized that this occurs in Alberta. Aka, within sane driving distance. :)

Awesome gun you have there. you gonna build more for sale?

***** status = hard.

HAHAHAHAHAHAHAHAHAHAHAHAHA

That is fricken amazing, I cant beleive you made that :salute: :tup:

that's pimpin with a capital P, I know I'd shit my pants if that thing was anywhere near me.

I'm considering making one of my own, only a I need to find the cheapest possible methods so it could be made in larger numbers for possible sale. Would you mind listing off some problems you encountered for the sake of an aspiring inventor?

Number one problem is getting the mechbox in the gun and have the AEG barrel line up with the m2 barrel placement.

As you notice the Barrel of the m2 comes out near bottom of the recieve where as most gearboxes have the nozzle/cylinder etc at the top.

Other then that if you got some mechanical ability its a piece of cake if a bit time consuming.

Alright, thanks. Once I get some shit together, I'll try and make some marketable ones.

I've also come to a conclusion: the airsoft community needs more artillery. Thus, once the initial prototypes are finalised, I will be making and selling mortors, howitzers and so forth for the members of this forum. They will be sold AT COST.

Awesome job! Wow.
I don't want to be against you in combat if you use it...

You should nickname that thing Viagra....the more I see of it, the harder my manliness becomes. Nice work.

The Q project was supposed to do a Ma Deuce, but never did. They wanted like $3000 US for it anyway, which is slightly North of OUTRAGEOUS.

If some Yank lads wanted to attend one of your games, how tough is it to get into Canada with Airsoft guns? Is it even possible at all? Likewise, you gentlemen are welcome to come to any of our games. Bring Mama D with you. :-D

Claymore
(It's a KILT dammit.....A KILT!)

very nice work sir

that thing is a monster!....a beautiful monster at that! how did you construct that? can i get some blue prints or something? I mean WOW!

nice gun

the gun was out at the EAR game on the 19th, f*ckin amazing to see it in person... an amazing support weapon.

Excusme while I wipe the drool off my keyboard, but that is F***ing Awsome :tup:

I want one of those on the back of my truck. Now what would be cool is if you stuck a rocker plate on the the tri-pod so the whole gun shook as you fired :D

Wow... nice.. lol bb spammage :P

good job!!! its really nice

Very good job with that .50 cal :-D I´m thinking of building one myself, but I have so much other projects so I dont know when I will get the time :-(

I have nothin to say but... I hope i never run into this in the field...

Sweet

hey blastyman
 

hey look me and my friends are creating a vehicle for airsoft and we are wondering how much you are willing to sell your 50 cal and or how much would it cost us to have you make another one ....we are willing to pay for labor and cost of materials so whatever you feel is a valid price we will also cover the shipping since we are in california to put it in perspective could you tell us how much it would cost american that would be much appreciated ill pm you my email if you are interested in helping out fellow airsofters it would be much appreciated thank you so much

Where do you live, exactly?

blastyman or the other guy above you, hes from california, blasty is part of the edmonton team

so cool
 

man that is so nice....kudos

Wow. I imagine that would hurt extremely bad to take 100 shots from that as you round a corner.

it hits with a good amount of power... i took some shots in the back from it and you know you are hit.

its quite a beauty love to fire that thing

Let us know if you intend to publish the plans.
I'm an old armored cavalryman and would love to build on.;)

Rocket launchers and flamethrowers are pretty simple to build.
