The beef-up kit must be installed in the lower to maintain function of your GEN-12 upper. If they are not installed then you may have magazines fall out, have the bolt prematurely open, or break a trigger pin during firing. Apply blue thread locker to the screws of the antiwalk pins during installation and torque to 6 in-lbs, and be sure to let cure entirely before shooting.
