Anyone know where i can get my hands on a lower to this tec9/ab10 receiver I bought? My friend buys storage units and found this. But since he can't have guns anymore, "too many dui" he let me take it. I really want to complete it. But if it's impossible to find one I'll sell it. Been searching online alot. And since backpage went down it's going to be near impossible to acquire the lower I fear.
