9mm Lower Reciever

I bought this 9mm lower to build a new PCC for competitions. I chose APF due to the price (on sale), and their quality, having purchased an APF lower previously from my local store. I was impressed with that lower, so figured I'd grab this 9mm lower for my PCC build. Overall quality seems good and I had no trouble assembling it with my chosen lower build kit. Everything went together as expected, with the exclusion of the 5.56 mag release, which isn't needed. This lower comes with a glock mag release installed. I really only have two issues. One: this lower doesn't support last round bolt hold open, as some others on the market do. This isn't a big deal with long competition magazines, but is something that wasn't noted int he product description. Two: the magazine area is milled pretty tight. I have found that only about half of my magazines drop free. Due to tolerances in the magazines, some of them are a tad larger and stay wedged in the lower and need to be pulled out. Other than those two issues, I am pleased with the lower. It matches well with my upper and does what it should.
