Works perfectly fine compared to other high dollar brands. Fitment is spot on.

Great Value


Fit and finish were great. Threads lined up easily and installed with no issues. Pretty great value for the price

Is This different from all other buffer tubes?

Why is there no lip to catch the detent pin, that stops the buffer from going in to far to close?, Since it is not there the buffer must be tightened in so far that the rim of the buffer catches the upper when trying to close.. I have never sen one like this before...
