Hey; I’m just trying to help. If it’s not properly installed you can end up with a gas leak and fouling. It’s not uncommon for inexperienced PSA shooters to need someone with more experience to help them with the initial installation.
And it can be a tight fit at first. You don’t want to get it jammed up at a weird angle either. Then you have gas leaks and fouling that can lead to lots of residue building up and causing it to stick even worse.
I have one of their complete ARV (9mm) and it runs like a scalded ape, and not stupid gassy with the can on it either. I love the fact it uses (smart move, PSA) Scorpion mags. My Scorpion also approves of the PSA made mags, no issues. Been buying uppers and parts from them for, ever? Never and an issue or complaint. Picked up some G-clone lowers from them so I could sell of the rest of my Poly80 builds (my G-gun fanboi days are loooooong behind me - live and learn).
