    Has anyone used a lar Ops4 upper to do a build. I need some information on my first build. I bought a ops4 upper with bolt assembly. And a stripped Lars lower I used a cmmg lower kit now when I mount the upper on the lower the bolt won't pull back. I took the bolt catch out and it will work.did I use the wrong lower kit.
