Can i fire 5.56 out of my Colt 6601c 1 in 7 Hbar?
I'm still confused as to whether or not i can fire 5.56 ammo out of my rifle. The lower receiver has .223 stamped on it, but it's a 20" inch Hbar with a 1 in 7 twist.
You would think that Colt's could handle the higher pressure round seeing as they are one of the most expensive AR's.
I fired 5 different kinds of 55g loads out of it last weekend after buying it.
they were Tula 55g, PMC 55g, winchester 55g, Remington 55g, and American Eagle 55g.
The American Eagle is the white box that has on it 5.56mm(.223 Remington)
is the American Eagle modeled after 5.56 of some sort? I'm confused and would hope that this Colt Hbar could handle 5.56 without blowing up.
I'd feel really stupid if i bought this Rifle now knowing of my mistake.
Any help would be great. Thanks.
