I want to sell or trade or add cash to a trade for these Stag Arms AR10 receivers for an AR15 or a AR15 complete lower receiver. I won't trade for PSA or Anderson. I will entertain other offers. The upper comes with charging handle, forward assist and dust cover. The lower receiver includes the proprietary pivot and takedown pins with springs and detents as well as a threaded bolt catch roll pin. Lower receiver accepts LR/SR magazines. 
I could add a magazine release mechanism and button, aftermarket or stock trigger guard, aftermarket or stock bolt catch and safety selector lever. At additional cost. 
I value the receiver package as advertised at 450$ but im mostly looking to get into a AR15 build. 
text is preferred 907-715-6510 and I'm willing to travel to get the right deal done.
