So I'm looking to make my own 10/22 receiver which isn't the issue. What parts could I get for dirt cheap just to check for function? I know on sites like midwayusa AR Stoner makes relatively low cost cheap AR parts such as everything from pins, to triggers, to barrels, and everything in between. Is there a company like that which produces average parts for ruger 10/22s? I know you wouldn't exactly want a poor barell, but for the pins, bolt, trigger, and everything else I'd like to keep it real cheap.
