I have one complete set of Colt M16 4-Way Fire Control Group parts including the Colt 4-Way Sear. These allow your registered receiver to have four positions (safe, semi, 3 rd burst, & auto). Unlike some of the problematic kits from DPMS or Tapco, these Colt parts work flawlessly. The parts fit the mil-spec (0.154) small pin receiver holes. Includes all parts shown in the picture below as well as 2 spare hammer springs, 2 spare burst cam clutch springs, and 4 spare disconnector springs. Parts are used, but in excellent condition.
These parts would cost well over $300 from Specialized Armament Warehouse, but I will sell for
Note: All NFA rules apply. These are not conversion parts. They are for registered receivers only (should work with an RDIAS as well). I will not sell to states that don’t allow MG ownership, so don’t ask.
Not interested in any trades. I will take cashiers check or postal money order. Shipping is by USPS Priority Mail with Delivery Confirmation. IM or e-mail me if interested.
