Star M249 upgrades??
 

hey ive looked around a lot and i cant find anything about upgrading a star m249, ive managed to find a metal mech box on redwolf, but i have no idea what version of gear box it is, or what parts to buy for it

you can actually get new upgraded full mech boxes from star

what site

i got that right from star when I was looking at buying their MK46

ya but who would i go through, caz i cant buy directly from star

I would suggest asking Ken at www.007airsoft.com and see if he can order you one
or any other of the parts distrubitors....... www.google.com

k thanks jayhad, but im still want to know the version of gear box anyways, caz i think i want to get torque up gears and get 400fps spring, ya star makes interchange gear boxes but they are still plastic, i think i want a metal one, so i need to know the version it is so i can get for it

Looks like a CA249 gearbox to me, someone please correct me if I'm wrong. I read a few reviews on the star 249 and it doesn't look like anyone has had trouble with the gearbox shell itself, just the parts contains therein.

+1 CA M249 MBs. They don't break

Yes agree with Cactus, CA internals are not that great. I would even say the quality of the M249 MB is not the best but its just so damn thick. The nice thing about CA is that everyone carries there stuff and its not hard to find individual gears if you only strip one.

I would focus on a ROF of 25rps depending on your FPS limits. That ROF is about 50% greater than most AEGs on the field and its not unpractical. Most stock guns run from 15-18rps on an large 8.4v. Test yours by using these instructions. http://www.airsoftmechanics.com/home...nt/view/24/30/ A 9.6v large type battery will usually give you +2rps. Helical standard gears and a high performance motor will help. A mosfet would be ideal for this setup as well. It will increase ROF by 20-30% by improving efficiency. A light piston and large bearings will help too.

I try to keep my ROF as close to M4s as possible, you know, like the real M249?

The CA249 mechbox is more or less a solid block of metal. It's like 90% metal and 10% space for your internals :p. Seriously though, it accounts for like 1/5th of the weight of the CA249, and given that the CA249 is itself a massive piece of metal, thats saying something.

Anyways the CA249 box isn't going to break anytime soon. However, its hard to say if its due to the sheer thickness of the thing or due to the design (I'm inclined to go with the former). Having said that, the Star M249 mechbox is plastic (and clear plastic at that :p) and may be plauged with all the structural issues of your regular V2 mechbox.

Oh, and regardless of which 249 you choose, make sure you can fit a full sized 9.6v battery in there. If your a SAW, your gun will see plenty of trigger time. Having a high ROF won't hurt either.

Upgrade those gears too. I didn't bother with heavy spring upgrades. Generally, with a fast firing weapon, you'll want to focus on efficiency and air compression rather than high power.

I don't get why people want to make ROF monsters of 25RPS+

It's harder on your gun.. and it's just as effective of suppressing people as something shooting 10RPS... + you go through a metric shit tonne of BB's already.. why waste more?

ya im talking about the star m249 anyways, not the ca one, there is a plastic gear box and im going to get a metal one, i need to know what version the gear box is so i can get the right parts for it, does anyone know what version it is

I commend you for trying to keep airsoft in the reals of a simulation. I think airsoft can offer a lot to law enforcement and military training where simmunitions are not appropriate. The M249 and the M4 do have a rate of fire of 700 to 1000 rpm. This is roughly stock performance. How would you upgrade your M249, just durability (swap parts) and 60FPS (to ~400FPS)?

mateba

Its ok if you don't get it. This is the upgrade/mod section though. There is a tactical advantage to higher volumes of fire. There is a fear affect generated by ROF monsters much like the whistle of a .3 at 450FPS. SAWs are expensive and, yes, buying more BBs or parts to support a higher ROF system would come with the territory. The parts issue might turn some people away but some people really enjoy this side of airsoft.

ya i would get a 400fps instead of the stock 280fps (i think that is what it is dont quote me on that) and because of that i would have re-enforced gears
thats not the point, it doesnt matter what im going to do, i have my own opinion lol, im just wondering if anyone knows what version gearbox it is, so i know what parts to get for it

Sorry for so many posts

I believe you can use the CA MB if you want. STAR makes drop-in plastic MBs for the CAs and they appear to be the same. PGC refers to them as V3S but mostly they are listed for the "m249 series" because no other AEG uses that design.

--

The STARs are one of the lightest M249s out there so I think you are doing yourself a favor in the long run. But, you know that after you spend money on the upgrades you'll be at or over the CAs price range, but I would not but a CA for its internals (the M249 MB being the exception). Does STAR ship with box mags, CA does. I think if you upgrade your STAR you'll be happy to have the best of both AEGs.

good luck

thanks mateba, finally something that was had useful infomation

still i would like to know if i can uses version 2 parts or not

Sorry to hijack your post

If it is a modified V3 then it'll take v2/3 parts.
The tappet plate is a Ver 2 and the spring guide is a Ver 2 as well and it has a CA short type motor.

I have upgraded the star249 gear box. First get wildmonkey metal gearbox for sure, polymer is shit, piston guide rail failed after 4000 rounds.

As for internals you can use any gear set you want, the stock gear set is pretty good though. The piston is V2/V3 however not every piston works, I tried a few systema ones and they were just a little too short and would get hung up on the side of the mechbox. (I used a VSS piston and piston head)

You can use a version 3 spring guide you just have to cut the sides down a bit (you will know what I mean when you go to install it.

Now the mechbox is long therefor you will loose 40-50fps off whatever spring you use (I'm using prometh 140 shooting about360fps)

Standard barrel so thats an easy thing to upgrade, the hop up rubber is shit, get a guarder one.

I havent changed cylindar and nozzle yet so I dont know what comparable version it is yet,

also install a mossfet

Dude, that sucked. I now understand what you were wondering. That thing doesn't have a version and there is no way to know what you have to put in it. I think its mostly ver 3.

The CA M249 uses V2/M4 gearbox parts. V2 tappet plate, M4 nozzle, Gears don't really matter, V2 Anti-reversal latch, short motor. The stock barrel is (i believe) m16 length. So if your going for cylinder upgrades, get one ported for that length.

k thanks jerryliang2k and mateba, this is really helpful

Star's don't have a plastic mech box... it is poly carbonate a major difference.

Star uses it's own mechbox design so you can NOT just grab a v2 and drop it in there

PGC makes a CNC'd mechbox for the star but IMHO it's a waste of cash as the star boxes are pretty damned good

If you are so decieved that the Star is plastic and you can't work with that check WGC for the PGC mech box

WTF???

Sorry I couldn't reply sooner!
I put prometheus double torque up gears and piston to increase the durability to nearly unbreakable, systema 'silent' head set (cushions the blow better, maybe 10% quieter than standard piston heads). And she only shoots 350fps due to MAA rules, but if we still had to 400fps limit I'd only put it up to 370-380fps both for durability and for safety's sake of other people. I also cut my 8.4v 4200mah battery down to a 7.2v to keep the ROF around 800rpm.
When I first got it I had just shimmed the gears and put a 350fps spring in it, so I was just using a mini battery and getting an ROF around 800rpm. Well the mini ran out so I switched to my 8.4v 3000mah, ROF went up to about 1000rpm lol

got to say if your a small framed guy the star might be for u. I have only had 1 problem and it was my fault for being impatient with the trigger assembly. With a tightboar and a new hop up it shoots far and last long.

k thanks, this is what info i was looking for, thanks jayhad

Acer i typed wrong the star CAN NOT use a v2 like i miss typed in my previous post

shitty, what parts can i use then
