Is there much of a difference between BCM and a CMT bolt beyond price?  Both are Mil-spec shot peened carpenter 158 hp mp tested.
The MP engraving even looks very similar
Top pics is from BCM bolt and bottom pic is a CMT bolt

how many broken bolts have you seen on this forum?  I've seen a few DPMS that broke at the cam hole and some Colt with broken lugs.  The Colt's were shown by a military guy and they were high count well used bolts.  Also read about some crappy bolts on the market recently, but they were some no name crap.  Otherwise no bolt issues

So in summary: you are dwelling in the zone of irrelevant differences

CMT makes their own bolts, their HP MP bolts are used on the Stag Arms Plus Package Mil-spec bolt upgrade which customers could only buy as an option when buying a complete Stag rifle, the upgraded BCG are not sold separately.

BCM currently have a different BCG supplier not CMT.

Where did you find the CMT bolt/ BCG?


ETA:

Microbest makes BCM BCG.

I got the bolt from Stag it came engraved with CM on it which I assume is Continental Machine.  You can buy the HP MP tested bolt for $50.00 on their website.
