AT3™ ALPHA Shake Awake Red Dot Sight

AT3 ARO™ Micro Red Dot Reflex Sight

$149.99

Tough and Versatile – A Great Option for Gas Blocks and Low-Profile Optic Risers

Built like a tank – this riser mounts up to the gas block securely, giving the front sight a solid mounting point on the same plane as the upper receiver. This riser allows you to use a same plane front sight on all YHM railed gas blocks. Made from aircraft quality aluminum and Hardcoat Anodized matte black to Military Specifications or higher.

This product is also great for firearms requiring just a little more height on their standard picatinny mount when using a red dot sight. For example, you can use this riser on a Ruger Pistol Caliber Carbine in conjunction with our RD-50 for optimal mounting conditions.

GAS BLOCK RISER

This device worked perfectly to give just enough rise for the front sight, to be level with the upper rail. It mounted in moments, is of great quality, and I am very pleased with it. Thank you Yankee Hill Machine for making it, and AT3 Tactical for providing it.

Thanks for sharing your feedback! We're glad you're satisfied with your purchase.
