I have a S&W 5.45x39 retrofitted with a REV2 Adams Arms Piston Kit. I have a total of 4 Adams Arms Rifles, 2 of which are SBRs, I have 20K through all of these guns and the only malfunctions I have experienced were caused by ammunition, that being garbage PMC rounds I bought from Jim's Gunjobbery in Fayetteville NC. I have put Centurion, Wolf, Brown Bear, Priv, Remington, and Hornady through these systems. I have shot handloads too. They all function flawlessly. I am also in possession of GB-001A, Adams Arms first production system, so technically I am their first customer. Jason and Jim are the Best!

I know this because I am about to buy one using the military discount from Smith and Wesson which is 40% until 31 Dec 2009. If there are any retired military or active duty components out there look up this deal, or email me for more info at deadlystrategy [at] yahoo [dot] com I'll get you hooked up. don't email me unless your actually military or your wasting your time because you have to show a copy of your ID.

It comes out thru the gas block, and you can replace the gas plug assy and put it in the closed position when you're using the 22LR conversion, and replace the op rod thru the gas block when done. At the very least you'll need to put the gas plug assy in the off position to prevent the op rod from striking the conversion unit.

They just believe the perception that pinned blocks are less likely to loosen is worth the $ in the target customer's eyes. Because of that, even though they don't think it is necessary from a reliability standpoint, they're going to do it anyway.

I talked to them at the SHOT Show, and Adams supplied the original design with a few mods: "skis" on the back of the bolt carrier to prevent or reduce the propensity of the bolt carrier to wear out the buffer tube, a unitary bolt carrier (no bolted-on key where the rod impacts) and the block will be pinned on. The S&W rep said that the pinning of the block is more of a sales issue than a real mechanical upgrade. It IS a modified Adams Arms design.
