Question for the AR 10 builders out there. Will a Dpms barrell fit on a Armalite reciever, is the barrel extension universal? |

The barrels are interchangeable between the SR25, AR10, LR-308 uppers, however, there are differences in the headspace, so you want to keep the BCG's matched to the barrel.
ArmaLite Inc. uses a deeper bolt face than DPMS does on the LR-308, as they understood extractor geometry and its relationship to bolt face depth. |
