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?

by -

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...

1st build

This was for my 1st build. Great price and it works great.

solid construction

sturdy and came quick!

No catch, but it still works!

Great Value, but be warned, it is a bit less builder friendly. There is no cut out catch. A cut out catch isn’t necessary (and you could dremel one), but it does fit a little too tight or too loose. Still a great value and would recommend.
