Does anybody have experience firing a gas piston operated AR15, particularly one made by CMMG?
I hope somebody there can give me a feedback. Positive or negative feedback would be just fine.
Thanks.:o

I have a Stag Arms Model 8 and it uses the CMMG piston system. So far far it has 1500 rounds through it and it has been flawless. It's accurate , reliable, and easy as hell to clean. You won't regret it man.

Rarely will a piston gun shoot more accurately then a average DI gun, but if you like loitering on the 50/100 yard bayonet line who cares.

I have the Adam's Arms piston setup on mine, works flawlessly, like stated above, way easier to clean, got about 5000 rounds through it, no issues. Has significantly less recoil than my other AR and operates way cooler.

i have a adams arms GP upper as well, works great and i shoot out to 500 yards often without to much issue.

dont turn this into a GP vs DI which is better crap.

both guns will work for target shooting, buy what you like and have fun.

I think the cleaning aspect would be nice

I have and like the Adams Arms setup. Very easy to take down to clean when needed and runs great.

i have a CMMG GP upper and its a perfect shooter.. hardly ever a jam and very simple to clean...

CMMG is good to go and very reasonably priced compared to "other" Piston setups...

I have a stag 8, Stag and CCMG developed that system together, but now Stag makes their own on the same pattern. Works flawlessly

Its not about better, its not about shooting fast, its not about combat reliability, its about Accuracy at distance(not 50/100 yards).

Get off the 50 yard bore snake and bayonet rifle range and try a 200-500 yard NM course of fire.

Any proof to support this?

in theory this sounds really good, but there are too many other factors to make a blanket statement like this.

Its not about better, its not about shooting fast, its not about combat reliability, its about Accuracy at distance(not 50/100 yards).



Im assuming we are talking M4 style (14.5 - 16in barrels) here since that is what is popular, if so it is NOT a precision gun.

Now, we really do not know what OP is going for here, but I find it funny that you have made up his mind for him without any info.

I have the CMMG piston upper. Few thousand rounds through it with no problems. Its pretty cool to shoot all day and break it open and not see any carbon inside the upper.

For you guys running the CMMG uppers, any carrier tilt? The one I used to own had masive amounts of carrier tilt.

Random comment, but I'd like to see you hitting 800Yd targets "man sized" with iron sights, because I can and do it frequently.

with the redesign of the bolt carrier, carrier tilt is a thing of the past.
