Description

The parts should be printed a 50% infill and PLA. The bolt shim will need to be glued to the bolt wings with the flat side down. This aligns the bolt so it does not get wedged where you cannot move the bolt aft. The bolt handle spacer will require 2 10-32x3/4 cap screws with lock washers. The mods will improve the overall function of the BCA bolt action upper.
