AR45 range report
Well as I had mentioned in Alpha's thread, I really liked the looks of the FM pistol upper in .45acp that he linked and I ordered one. It came in and looked as good in hand as the picture and appeared well made. I got a Spartan Glock based lower, Kaw Valley Precision .45 buffer and spring kit, Stoner lower parts kit, and capped it with an SB brace. I was excited to shoot it and got my Glock 21 magazines in on Saturday. I had a box of Winchester 230 ball sitting around and on Sunday I made time to take it to the range. My excitement turned to frustration as it wouldn't run more than two or three rounds at a time without jamming. I tried all three brand new Glock mags that I bought and they all did the same thing, the tip of the bullet hung up on the edge of the chamber and jammed the gun. I thought maybe the edge of the chamber may have been a little too crisp and sharp from being freshly machined but the more I shot, the worse it got. I initially tried two rounds, then four, then a full mag of 13 rounds and they ran. The next mag would only run one shot at a time, and the next mag would only run one or two at a time and after a few attempts the one mag that originally worked fine was jamming after one or two shots. I called FM products this morning and the customer service guy I spoke with told me not to run white box Winchester and it should be fine. When I told him that I wanted to know why and that I wanted it to be able to run anything in it, he said that white box Winchester just didn't work and offered a refund for the upper. Now in their support, I had talked to a tech guy at FM previously about which buffer to use and they were extremely knowledgeable and helpful and this guy offered no technical reasoning and said a refund is the only solution he can offer. I'm currently awaiting a call from one of their tech guys to find a solution.
