Gentlemen its been a few moons & sunrises since active duty in the Marines but having seen the writing on the walls I returned a Windham Weaponry-223 AR rifle (disguised as a Bushamster)
and bought the rifle that we rolled in the mud,rain,heat(100degrees),snow and took this baby apart blindfolded and the dam spunky rifle kept on ticking-- the Colt M16. Well today I bought the
Colt M4-6920-AR rifle. This rifle has a 1/7 twist and I am asking ammo opinions for this rifle that will be part of my home defense.
Thank-you & Semper Fi
