THANX IN ADVANCE GUYS K: Its highly unlikely you will have any problems buying milspec BCG, upper receiver and barrel from 3 different name-brand makers. The chamber dimensions are set when the barrel extension is fitted to the barrel. Only a poorly made bolt would change that. If you get into reloading your own ammo, you will need a Hornady headspace gauge to ensure your sizer is setting the shoulder of the cases back .003 to .004 inches. It works with your dial caliper. Without sizing your cases in this manner, you could end up with either excessive headspace or cases stuck in the chamber. - CW http://www.midwayusa.com/product/479704/hornady-lock-n-load-headspace-gage-5-bushing-set-with-comparator |
