Out of spec
I bought this to put on my Aero lower and several of the pieces fit way too tight and out of spec. The safety detent pin/spring is one of the worst, its nearly impossible to turn it to fire/safety and the rear takedown pin is very tight, making it nearly impossible to take out. Hard pass for me, I had to buy pieces from my local store and now everything is good.
