Just ordered a standard BCM 16' Upper, and looking to remove the fsb, so which BCM gas block to buy, 750 or 625? You can have a "Standard" barrel in either Government profile which is .750 at the gas block journal or "light weight" profile which is .625 at the gas block journal You can also get a BFH aka cold hammer forged barrel in "Government Profile" or "Light Weight" configuration with those same gas block dimensions A few yrs ago BCM offered light weight barrels with .750 gas block journals.... |
