The whole BCG is over analyzed by alot of outfits including LMT.
What can't they just make a regular Colt/GI grade bolt carrier? This works 100% of the time.
Instead they brought us the "enhanced bolt and carrier" and do proprietary undercuts on their bolt lugs. Now they are tampering with the coating inside the carrier.
If LMT wants to improve, they can start using taper pins on their barrels or start profiling their barrels correctly.
