Thanks. I was kind of looking at the Rock River stuff the other day. Glad to hear positive feedback on them. Not sure if they would be compatible with a Glock mag lower but I bet a little minor machine work on the bolt would make it work.

I planned to buy a PSA upper for mine. The one I want isn't in stock at this time though. I figure their lowers and uppers are designed for each other and I don't have the tools or skills to machine out an upper.

I've seen some spotty reviews on the PSA uppers in 9mm so I think I'll just steer clear of them.

I'm not really set up to do any real machine work but I think the modification to the bolt to work with Glock magazines is fairly simple and straight forward and I probably know a couple of machinists that would hook me up for a reasonable price.

The newer G9 hybrid BCG on their uppers have been getting better reviews. Also, steer clear of the ETS mags apparently. Watched 2 reviews where those were the issue and not the gun.

Picked this up in a trade yesterday. Don't know if I am going to use a standard AR upper or pay for a NFA 9mm upper. As far as compatibility goes, I am almost certain NFA makes Joebobs and PSA. I can't find any complete uppers Instock but I am not worried about who's upper I use, I'm going to run the NFA glock/hybrid bcg in mine.

I bought the billet lower and 16" classic 9mm upper back in July. Shoots great and feeds fine. It's really fun shooting 147gr with through the Osprey.

Westminster Arms off of Wadsworth had a few of the complete PSA 9mm that take the colt mags. They are really rough around the edges. The bolt felt like it was running through sandpaper when pulling the charging handle and then letting it go. I picked up an ATI "pistol" from The Reloading Zone instead. Takes glock mags. Runs perfectly and the build quality far surpassed my expectations. Price was outstanding. My buddy picked one up too. Dang thing eats ammo like a fat kid eats cake.

Do you have any pictures of the ATI?
