I had an old I fired bushmaster m2.... wanted an m4 style instead. For $478, I bought all the parts to build a 2nd gun. Now I will have a 16” collapsible stock m2 shtf gun, and a scoped 20” target AR. Funny thing, last gun show, I could have bought a like new (could have passed for new) Anderson for $500. Saw another at $500, and another at $525....this was gun show prices. ( negotiable)
