Buy them @ White Label (Click Here)

Sometimes people confuse Sharps Bros with Sharps Rifle Co. and think that we are producing bolt carrier groups - we aren't.  The manufacturing of BCGs is a very specialized business.  So when I personally need a BCG for one of my builds, White Label is my first stop.  You might not have heard of them but they are producing very high quality BCGs for a lot of major firearm brands.  I've toured their US facility and it is world class. Large selection to choose from: check them out through the link above. - JSharps
