* All NFA Regulations apply. Each state’s laws dictate what can or cannot be possessed in its own state. Some county’s within each state are different as well.

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.
