I was lucky enough to snatch a CCA lower receiver and wanted to do the build myself
I've already installed a SSE Geissele and the 2 stage feels so crisp
I also decided to install a Vltor stock and here's my first dilemma.
There's no detent pin and spring on the receiver, now what?
I would also like to know if I should just buy parts separately since I bought my own trigger or should I buy a full dpms kit?
