1. are colt M4 forearms truly double heat sheilded? And if the reciever is stamped .233 and the barrel 5.56, can you run any ammo down the pipe??????????????? Sincerly, Dummyhy.gif |
Doe Colt mark all their barrels with chamber and twist rate? Are the colt barrels manufactured and stamped .223. |
| yes whatever is marked on the barrel, is what the chamber is.. ALL colts have a 556 chamber. you can shoot 223 or 556. 556 to put it simple is a little hotter than 223, so if you fire 556 in a 223 chamber you might have a problem, but not the other wat around. it is not an issue with colt. I sent you an IM cause you accidentally emailed me. if you want to talk more about it IM me, |
