Good Quality by JP, October 9, 2020
This thing is nice. It's easy to adjust and fits perfect with no wiggle. Definately not that crappy airsoft quality stuff you see on some peoples guns. I would definitely recommend and purchase again.

Not square on receiver. by Geoff, January 21, 2018
The quality appeared to be very good. Unfortunately it did not set on the receiver square. I am not sure if I got a reject. It was returned and refunded by optics planet. Great service. Tried on multiple receivers with no luck.
