It works, kind of - ProMag Archangel Pistol Grip Adj Stock Ruger PCC 9MM Carbine

Purchased this a few weeks ago to change up my PC carbine. It’s easy to install, it looks good and seems pretty durable for being polymer, I did need to tap the receiver down a little to get it snug but that’s a good thing. There are two major issues that would prevent me from recommending this product. The first is the bolt catch has an issue actually preventing it from allowing me to close the bolt, for some reason when it’s installed it allows the mags to over insert somehow. I’m not an engineer but I cannot figure out how this is possible, it happens with all my mags Glock/magpul/CTI and my Promag drum. As you can see that I tried 4 manufacturers so i ruled out mag issues. The other issue is with the mag release, when the bolt catch is installed the mags drop free, when it’s removed the mags bind. So for the convenience of having a pistol grip and adjusting stock I have to give up LRBO and pull my mags. Not good in my opinion.
