I've got a DPMS 20" HBAR postban barrel. Does it have a .223 or a 5.56 chamber? If it is .223, what would happen if I used 5.56 in it, for an extended period? Thanks |

No problem shooting 5.56 NATO ammo. I have shot mil-spec ammo in all of my AR variant rifles, including some late 1980's Olympic Arms bbls (20" Heavy "service match" and 16" heavy, both Stainless). I have never seen anyone else have problems with 5.56 NATO ammo, either. And your DPMS bbl is chambered for 5.56. |
