i think PSA is definitely experiencing some growing pains. they have had some issues with orders,most notably the wrong gas tubes on a couple of middy uppers. But they definitely will make it right.
they really remind me of SA in how they stand behind their stuff.
I will give them a BIG +1 also they got me my order in a timely fashion and it went together great. Now just hope it stays the same when I order my uppers.
They are a little slow on uppers compared to AIM but that is because PSA builds to order. They are fast compared to most anyone else that builds to order. I have heard of waiting months for Spikes to build an upper. PSA is usually two weeks or less.
