Looking for an M4 style folding stock AR15 lower. I will take either a stripped one or a complete but I only have $150 for a complete. Any low end brand is fine. Mega, SurplusAmmo, AeroPrecision, Dousble Star, CMMG, Del-Ton etc ....ftf, cash sale etc

Like this one from surplus for $165, complete: *Surplus Ammo & Arms AR15 Complete Lower with Collapsing Stock - Surplus Ammo
