$65 shipped for lower, $85 shipped for lower and upper. King Arms metal M4A1 stamped receivers (not that cheap laser engraving). Colt grey/gunmetal grey (not black). I have three total. All three are in solid condition (8/10). Have matching uppers for each one as well. Correct M4A1 trademarks. Was going to use for a project with someone but that’s fallen through. I have all necessary body pins for the receivers as well as charging handles, mag release, etc. *TRADES I’m mainly looking for HPA-related items (tanks, regs, IGL...) 1 receiver set pending
