Manufactured in Wyandotte, Michigan prior to the 1986 registry cut-off, and currently not installed in a host firearm. While deceptively simple in construction, being an aluminum block holding a steel trip sear and a small spring, its pre-86 registration status makes it an express ticket to build nearly any configuration or variation of AR-15, M16, M4, etc., including in calibers and patterns not even conceived before 1986. The possibilities are virtually endless.

Very fine with handling and machining marks. NOTE: This weapon is a National Firearms Act (NFA), fully transferable Class 3, which is registered with the Bureau of Alcohol, Tobacco, Firearms and Explosives, (BATFE) under the provisions of 18 U.S.C. Chapter 44 and 27 CFR part 478.
