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.

I want the piston system because it's more reliable. That's why I use the M6A3. Why does everybody not want to clean their rifles?

I want the piston system because it’s more reliable.

That’s why I use the M6A3.

It makes the Gun so much eaiser to Clean and NO more carbon build up in the Bolt! I highly recommend it. glwbear 34 years Law Enforcement & the Private Sector I have a ADAMS ARMS Piston system in a AR Pistol and after some minor adjustments it is a super system to have!

However, it does make it easy to clean. Valhalla, AR15 piston does not make it cleaner nor more reliable. However, it does make it easy to clean.

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 :)

Or something else nobody has thought of... As always when upgrading or changing something, rigorous training and testing in the environment you intend to use your tool is prudent.

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!
