LMT Defense Lewis Machine and Tool Full-Auto 5.56 Bolt Carrier Group
While some consider high pressure proof round firing and subsequent magnetic particle inspection to be archaic, US military rifles have always had their bolts undergo this strenuous test to absolutely ensure durability in the field.
Lewis Machine and Tool (LMT) is one of the few manufacturers that does HP/MPI testing one all their bolts and bolt carrier groups, not just batch tested. This ensures that each BCG is free from defects before it is sold on the market or placed in the hands of law enforcement or military. There are many budget BCGs out there now, some being imported from China or Taiwan -- don't skimp on one of the most critical components in a rifle for something you were told is "just as good."
If you're looking for a proven, premium bolt carrier group to serve as the core of your rifle, the Lewis Machine and Tool Bolt Carrier Group is hard to beat!
