CANDIRU M16 BOLT CARRIER ADAPTER
PEMBIE000INDUSTRIES
the purpose of this file is to allow an sp1 cut bolt carrier, or semi auto cut bolt carrier to still be able to trip the auto sear on an nfa lower or the super safety in a compatible ar15. this part is not regulated as it is just adding the geometry back to the part that companies try to cut out on purpose to save their ass. this is only secured by an m3x35 screw and nut that clamps the 2 parts together in the bolt carrier and do not allow it to wiggle, if your part wiggles or has any geometry change needed then the step file is provided and will allow you to make the necessary adjustments.
