Yesterday I started putting together a lower kit from PSA on an Anderson lower. The front take down pin was oversize and the slot and the flat part on the head did not line up. I had to grind it to fit, the same thing with Bolt catch. Other parts fit poorly and were roughly finished as well. Fortunately I had some spare parts and had an upgraded trigger because that looked really bad. The stock rattled too. Some parts looked like bad Chinese stuff. The Delton kit I put together was nice, everything fit and looked nice. Same with the DPMS parts I have used. No more PSA for me.
