How do you upgrade a Gas CM16

Like the title says, how do you upgrade a gas m4

I have a G&G cm16 gas and i want to increase the range on it any idea's

and if you have links that would be helpful

Get a new hop up bucking and nub.

 

[MrCheesman94]

what type of nub though there H - R

Joke answer: Put a gearbox in it.

Real answer: Hop rubber and barrel.

 

[TacMaster]

I have very good results with an R-Hop. I've not got any experience with H nubs though.

 

[MrCheesman94]

ok cool i will try that and i'm assuming a 6.03 madbull barrel

Nope. Tightbores are for grouping, not range. look to a 6.08+. And changing the hop rubber in it will make little to no difference, as it already has a G&G Green in it.

 

[MrCheesman94]

ok awesome will buy one

So what do you think of this;

6.08 barrel

Madbull ultimate hop ruber

R-hop

any idea's on how to make this a DMR?

Longer outer barrel , free float rail system bipod, scope

 

[sp00n]

use heavier weight bb's, due to there mass they take longer to slow down etc ... but the price will be reduced fps

consider over hopping

 

[MrCheesman94]

Ok cool thanks for your help guys

You may be able to put in a stiffer spring on the hammer or adjust it's strength to up the fps. Will also up your gas usage though. Will it take co2 magazines? Or go hpa.

I wouldn't bother with doing an R hop, lots fiddling to get it right etc, I'd just get a decent setup and run that.

i would like to make it a HPA setup but that would need a new gearbox i think, and wouldn't the spring just increase the recoil as i thought it was the gas that changed the fps, also anyone know about NPAS

 

[Mr Monkey Nuts]

What exactly is the problem? What sort of range are you currently getting?

 

[MrCheesman94]

i love the kick and sound a gas gun has but i dont like the small ammo count or the range which currently is very poor im going to check the hop now just incase

There is no gearbox in a gas gun, you just tap the magazines with a Q/R connector and plug the hose into that, then dial the psi in to give you the desired fps.

The spring on the hammer will dictate how hard it hits the striker plate on the magazine, harder will allow more gas through thus giving higher fps and gas usage.

this is my old M700 with the mag HPA tapped:



just a google image of mags tapped for HPA:

doesn't the cm16 have the GHK gas gearbox or whatever? anyway, if you hate small ammo count then maybe hpa tap a hicap? PT has done that and I'm just echoing his post above. ALso as previously stated the range will be your hop up, give it a clean and clean the barrel or get that new one...

 

[PT247]

this would require tapping each magazine with a Q/R connector, other alternative would be to make a hi-cap magazine by either double stacking an AEG hi-cap and feeding the BBs into the gas mag like I have done for my GHK G5:







or hybrid the 2 mags together which I am also trying to build so you have the top half of a gas mag and the bottom half of a hi-cap with the hose running into the inside of the mag

GHK uses a mech box.

just googled the gas CM16, it looks like a converted AEG so soz, it does have a gearbox. Going HPA would still be done in the above manor though by tapping the mags.
