I built an AR Pistol recently and have had no problems with it. This past week I installed a new pistol brace, the SBA3, which comes with a mil-spec carbine receiver extension. I went to the range today, and my BCG would just not function properly. It wouldn't travel far enough back to insert a round from any of my mags and it also wouldn't go far enough back for my bolt catch to be able to lock the bolt back. The only way it would shoot is if I pulled the charging handle back far enough to slide one round in.
This is my first AR, so I'm still relatively new to all the parts. I read another thread that said it might be because my buffer spring isn't meant for the tube that came with the pistol brace.
I have a complete BCM upper. VLTOR Charging Handle. VLTOR A5 Pistol Buffer Kit. All of this on an Aero lower and Geissele LPK.
I wasn't for sure if I should post this in the General Discussion or Technical Discussion, but I figured it would be seen first here.
I have a rifle class next weekend, so I would really like to have this figured out soon.
