Good on you! I'm now working on a AR pistol in 300 BLK trying to get it picking up the next round. For some reason it doesn't want to do that. Next visit to the range will include other magazines and at some point I may have to work on the barrel port.I started out looking to build a 300 Blackout upper to fit my AR platform, but it looks like the upper will be awhile getting here, settled for Aero Precision. Then today I stopped by SKArms and an Aero stripped lower followed me home. I liked the Rise Armament 434 drop in trigger that I recently bought for my 5.56 so much I ordered that and the Odin Works buffer and stock kit. So now it looks like I will have the lower built before the upper gets here, and I will have a complete rifle instead of an add on upper.
