I bought 2 uppers to go with my 2011 lowers, one for each kid, plus spare extractors and ejectors which I have not needed. I believe the breech is enclosed by the barrel extension, which is not the case with most 9mm ARs, but verify this.
Olympic Arms makes one. LRBHO works great. Buy the 10mm magazines if you load long. I milled a lower to use 2011 magazines so I will sell you some Olys for 1/2 price. Middle TN if you want to shoot one.
Thanks folks.... So the peening causes the left leaf to bend inward, the heat shrink centers the spring in the opening, and the metal shim forces it to the right?

Twice now, I have found that the sear spring has moved or tilted such that the left leg fell off the sear. (I can duplicate this with sloppy assembly) I searched the forum and found that I am not alone, but no clear fix was identified. Any help out there?

About 1/200 primers either don't get pushed out of the case, or they are stuck on the pin and reseated with pressure from the virgin primer on the priming pin. .40 S&W.... Any help here?
My shooting buddy brought a Palmetto Arms Glock-mag gun to my range today. He ran a wide range of factory and re-loaded ammo through it, and it ran great. He had to shoot the last round from some loads, but we should be able to solve this with the right OAL/bullet shape.
