Great value. - Aero Precision Adjustable Low Profile Gas Block w/ Aero Logo

In the world of adjustable gas blocks price and quality come together to bring you this one. It works. It will do the job of adjusting over gased weapons very well. I own three of them on various calibers. Aeroprecision hit a home run in my book. Installs easy and the extended gas adjustment wrench is great. Buy it youll be impressed.
