Full auto piston bolt carrier group. Developed for the Estonia Defense Forces, the new and improved design features a captive firing pin retainer similar to our .308 rifles. Drop in upgrade for all existing LMT piston rifles.
TEST FIRE DISCLAIMER:
Many of the manufacturers whose products we carry will have a standardized test fire protocol for not only their complete firearms as well as parts such as upper receiver groups and bolt carriers. Because of this test fire protocol, some items will show evidence of the test fire process such as brass and carbon residue on internals or brass markings on case deflectors.
