But it's actualy more like the Mini 14 gas system than a true piston system, like the M14 or the new Ruger SR556. I have the Adams kit on an LRB upper. Works awesome. 0 problems and runs as clean as an AR can. Anyway the "piston" in this kit doesn't move. It's more or less a "pipe" that the gas goes through, then it expands in a small gas chamber that is part of the transfer rod which gets pushed back thus cycling the bolt. Just like on the Mini 14 gas system. There's obviously a big difference in the way the parts between the two systems look, but the actual physics are the same. So the gas chamber moves, and the gas "piston" is stationary. The total oppisite of traditional (M14) piston systems where the piston moves inside of a stationary gas chamber and hits a transfer rod to cycle the bolt. I actually like the Adams kit more than a traditional piston system. It's simple and easier to clean in my experience. That's why I chose it. And I'm glad I did. The Adams kit shown here is GREAT!

There is no carbon in the bolt or bolt carrier. Just use your common sense, where do you want all the junk, in the front or in action, that lets the job get done? I'm 58yrs. old been to nam and see what the di system does, just get over it, and try something new.....and this does work, I'm totally amazed. Common sense will tell anyone, if you are going to put the carbon back in the action, the action slows, just think about it, and you will see! And to all the guys and gals that want to use the di system go ahead, but Adams Arms system works, and that' the long and short of it. If you don't like it, don't post, unless you have tried it, and I have and it works!!! I bought the Adams Arms piston Kit 2 weeks ago, and it just works!

I have 2 other uppers one a 16 inch barrel with a AK 74 muzzel brake and the other a 20 inch with a rifle length gas system and both are Direct Impengment. After compairing all uppers the Adams Arms piston retrofit does make the rifle run cleaner and cooler where it counts, the bolt assembly! The recoil isn't much different than a DI system but then the two DI uppers I have are Bull Barrels and one is compensated so they don't move much. The AA Piston upper is lowder than the others due to a shorter barrel length and I'm using a FSC 556 Bulldog Brake from Addax Tactical (designed by Primary Weapons Systems) but all of that asside if feel like I'm shooting my Ruger 10/22! I don't have much expierence with many other Piston uppers other than POF which is very well made as well so my recomendation is buy an Adams Arms kit.

For anyone not familiar with the Mini-14 or piston systems, I'll go into a bit more detail... Whereas a piston setup like the Carbine vents gas to push the piston into the op-rod assembly, the force of which pushes the rod backwards and operates the bolt, the Mini-14 has a gas aperture or valve which directly vents gas into a cavity on the op-rod. I guess you could say the Mini-14/Remington design eliminates the middle man, but it still cruds up the inside of your stock! The crud just isn't in the working parts of the action, which is the big argument against direct impingement. @Dom: Except the Mini-14 doesn’t use a gas piston :)

If only Bill had built an accurate gun, it would have been great. Adding this to your AR is very, very cool. Not sure about ROF but it definitely keeps the mechanism cleaner and thus more reliable. Blow-by definitely happens, Ken, I can tell you from experience with my Mini, but it doesn't hurt anything. This is one of the reasons Mini-14 owners like Mini-14s.

My only real worry is whether or not it'll fit under Yankee Hill free float handguards, which I'm rather fond of. My current rifle has a "smooth carbine" handguard, so if the kits by CMMG or Adams will fit under that I'll be saving up for one!
