As soon as the fortress nut is loosened, the buffer tube could be eliminated. It’s important to take care to not harm or lose any small elements.
Then, the brand new buffer tube could be put in. Screw the buffer tube into the decrease receiver, hand-tightening initially. Utilizing the armorer’s wrench, tighten the buffer tube to the producer’s beneficial torque specs. Correct torque is necessary to forestall the buffer tube from coming free throughout firing. Be sure you use a torque wrench for this step.
Subsequent, set up the buffer and spring into the buffer tube. These are usually inserted from the rear of the decrease receiver and positioned into the buffer tube.
