Great gas block by Zeffery, December 9, 2022
The front sight post is easy to install as well as easy to align. The Front sight post is solid and easily visible. It's tough to beat PRI in quality. The gas block definitely lives up to the MK12 MOD 0 billing in both looks and functionality.

Keeping it simple by Shadrach, Verified Owner, December 15, 2023
I chose not to use the gas block option of this part, but did want a front flip up sight that attached directly to the barrel so I bought this one. As with PRI.s flip up rear sight, this too is built very well and is quite stable and does not move on...

PRI set screw front sight by Ray, Verified Owner, January 15, 2021
I originally had the clamp on version on my MK12 but changed to this one because it is correct. It has one set screw on the bottom that lines up with the dimple on a Douglas barrel. I marked the spots on the side and put 4 dimples on the sides for th...

Product Info for Precision Reflex PRI Flip Up Front Sights w/ Set Screws

The Precision Reflex Flip-Up Front Sight is a top-of-the-line option when it comes to AR 15 Parts. Designed to work with the matching Precision Reflex Flip-Up Rear Sight, this same-plane aperture front sight allows for independent adjustment for windage to help you achieve an accurate shot. These sights are low-profile, so they won't get in the way of your red dot sight when you have them folded down. Plus, they lock in the up position securely to prevent accidents that could knock them down and throw off your shot.image
