M14 Question
 

Stock inner barrel length of the M14 GO!

520mm
Upgrading to a tightbore?

500mm

G&G M14/CA M14: 520mm
TM M14/China Clone: 500mm
CA M14 SCOUT: 463mm
G&G M14 SOC16: 463mm

ok cool ... I got the TM one and yes I was considering a tightbore... but I wanted to know so i can measure I might get 550mm then... depending on how far it sticks out of my flashhider.

Has anyone heard anything about the Tanio-Koba HOP Twist Barrel for Marui AUG / M14 / M16 Series ( 509mm )???? It sounds good being a twist barrel and all has anyone tried it out?

You cant get other inner barrels for an M14 from what i hear. You have to get M14 specific ones due to some difference in their design.

Read up on the twist barrels

correct me if I'm wrong but aren't M14 inner barrels cut differently from the other AEG barrels?
I don't see how TK can have a universal barrel for M14 and the other 509mms

M14's have a unique hop up chamber mount. If you're going for a longer length, you'll have to get the hop up end custom cut.

And on that note, you'll need to check your air volumes - not sure how much air the M14 cylinder can push out.

As for the Twist inner barrel - you can't use it effectively if you're shooting over 330fps.


I had this barrel before, and the cut was done effectively. I'll be damned if I can remember how they did it again, but if I think I remember correctly, they had TWO of the C-clip notches cut out. The only difference between M14 inner barrels and standard AEG inner barrels is that the M14 inner barrel's C-Clip sits closer to the hop up end.

So... I should just buy a longer tight bore barrel instead of the twist barrel??

so would a 500mm inner barrel be a good length given the whole cylinder air and stuff like that.

M14 Tuning
 

Hi!

I'm a Hungarian Airsoft player and I promise you can help me. I would like to buy a CA M14 rifle and tuning it. Where can I find a tuning guide about this rifle? (I would make a DMR AEG) Thanks for your help!

CA is a copy of the G&G.. Get the TM it will be less hassle down the road and you wont fry your motor after you upgrade the spring. G&G if left stock will be fine but once upgraded thats when the hassles start. I know from experience.

TM is alot easier to maintain and easier to find parts for. Also the mags are a hell of alot better.

The TM M14 is far superior to the G&G and Classic Army versions.

This question is primarily for ILLusion:
Alrite I have a TM14 and I just had a hop twist barrel put in it and also a new spring which brought it up to abt 350-360 fps. but that was before i knew that it was joules, not fps that mattered for the usage of the barrel.the shop told me just to use .25s to even it out, but after reading your research in the thread, i kno that joules are wat matter. so wat i am asking is, to get the most accuracy and distance (w/o that annoying bb lift at the end) should in itry to decrease it down to one joule again? also, wat should i do with the hop up, adjust it like normal, all the way up, or totally off? it is currantly in the shop again so i you could let me know wat you think wud giv me the best results, i wud appreciate it.

Hop up should be turned down to stop the "BB lift" at the end. Tune it right at the start of a game cause humidity and air pressure can supposedly affect your ideal hop up setting for the day. Turn it all the way off then shoot, turn it up until you get the straightest distance and a little bit of "lift" and then turn it back down a little to get your maximum effective range.

You're going to want to probably .25's or .28's if you're playing outdoor for more predictable shots even if you slow down the BB, it will get tighter groupings and better brush penetration.

Also if your shop told you to use .25's to slow down the speed then I would not use them at all (they don't seem to know the difference between velocity and energy). Go to another shop or find a new gundoc.

You could probably downgrade the spring, M120 is probably what you want to be aiming for. Otherwise a 1J spring (I believe this corresponds to a standard M100 spring) will do the trick and you should be able to play CQB too.

I would either downgrade your spring to one within the 1 Joule (328fps @ 0.20g BB) range, or swap the inner barrel to a straight bore barrel.

A straight bore barrel at 380fps will have greater effective range than a Twist barrel at 328fps, however, the effective range that the Twist barrel has will be straighter and more predictable than 380fps with a straight bore for the effective range. Beyond that, the 380fps straight bore setup will outshoot the Twist barrel.

Figure out what you prefer... a straight predictable flight, or a greater effective range. In my tests, my M14 shot 380fps with the Twist barrel and the flight path was very unpredictable. I would not recommend using a Twist barrel at that velocity.

With the Twist barrel, hop up is set as you normally would. Once you go too high, the BB starts to do crazy things.

I've got a Twist barrel in my M14 right now... It shoots at about 400fps with .2s. I use .28s and it shoots at 330ish with em... my groupings with the twist barrel are amazing... I also get a range of about 50m with very nice accuracy...

That does not reflect my experience with a Twist barrel in my M14 or any other high powered airsoft gun. You may have a magics setup. Don't touch anything in it... keep it the way it is!

Absolutely!
I originally thought that it would affect the shot like crazy but after I gamed it and had some nice kills at pretty long range and some quick close range snap shots, I found out it's dead on. I put a few rounds on target in my back yard with it just to see after that game and sure enough... consistent groupings.

*EDIT* Yep just went and tested it in my backyard again... It's got a grouping of a couple Centimeters at roughly 25m (length of my backyard.)
