The new Safariland AR-15 mounts are designed specifically for flat top receivers with Picatinny rails. Three models are available to meet the need of military, law enforcement and sport shooters. Machined from 6061-T6 aluminum, Safariland AR-15 mounts have skeletonized top caps and bases that reduce weight. Each top cap is secured by four screws to prevent movement of the scope or red dot sight. The corners are rounded to remove sharp edges and lessen the chance of snagging on other gear and webbing. The mounts are secured to the receiver with milspec thumb knobs with integral washers that can be tightened by hand or with a regular screwdriver.
