Adams Arms Piston Upper Receiver

Adams Arms - Adams Arms - AR15 Gas Piston Systems

Does anyone own one of these? I'm looking for some first hand reviews, good/bad/indifferent before I commit. Thanks all.

At the beginning, people have had troubles with modifying a DI rifle with these kits... Tolerances and whatnot. They may be good, now.

I now understand how useless this post was since you're looking at the actual complete upper... But I haven't heard anything negative about them.

If it matters to you it is the same system S&W is using for their PS. Good stuff.

i do know that they provided the piston system for Sabre, before Sabre went down. at rockcastle we got use a Sabre full auto with the Adams Arms piston system. no issues for us anyway. if it makes a difference each shooter provided there own ammo.

also i do not know were CMMG gets there's but at the Pro/Am the 7" full auto piston gun was one hell of a flame thrower.

Thanks all for the input. I've seen some negative stuff about their retrofit kits, but that could be operator head space and timing, not necessarily the kit. A former coworker of mine wrote a review on the kit on defensereview.com, so I'm not certain if the complete uppers were available at the time. He had a lot of good things to say about it but I guess I was hoping that someone actually owned one that was assembled at the factory to see what they think. With what I know I think I'm gonna splurge and pick one up after the new year. I'll be sure to post on it's performance since it seems that there aren't that many folks that have one.
