I had the ati milsport in 9 mil. I had dozens of issues in the first 100 rounds to the point I had to send the bolt carrier back for warranty work. It functioned better, but still not great. I saw the psa had an even shorter barrel and the sig brace. I took a chance knowing it wasn't going to lock the bolt open either. First 250 flawless rounds and I couldn't be happier. At 499, this is a steal but I recommend the sig brace, not the blade version. This was reliable and fun enough to forgive the lack of lrbho

isn't this a SBR since it has a buttstock? Requiring a Form 1 $200 tax stamp?

It's a not a buttstock, it's an arm brace and is a pistol so as long as it's not an adjustable stock like one would have on a regular ar15
