BCM A/T Optic Riser 525-13 5.75" Black Anodized 13-Slot Picatinny Rail

The BCM A/T Optic Riser 525-13 is a 13-slot Picatinny rail optic mount machined from aircraft aluminum alloy and finished in Mil-A-8625F Type III hard coat anodized black. Running 5.75" long, it spans the full length of a standard AR-15 upper receiver and adds an extra usable rail slot on top of the rifle's existing top rail, giving you more room to mount red dots, magnifiers, night vision devices, or thermal optics in front of or behind one another.

Designed by Bravo Company to raise the optical centerline of the mounted optic by 0.525", this A/T riser establishes a lower 1/3 co-witness with typical AR-15 backup iron sights while properly clearing night vision goggles and other face-mounted equipment. The low-profile, snag-free top contour keeps clothing and slings from catching on the optic during dynamic movement, and the Mil-A-8625F hard coat anodizing gives the rail the same corrosion and wear resistance BCM builds into their complete uppers. Whether you are running a red dot, a magnifier, a clip-on thermal, or a night vision setup, the 525-13 keeps your optic at the correct height without compromising cheek weld or trigger access.

Made in the USA and backed by BCM's reputation for hard-use rifle accessories, the ORAT52513 installs directly to any standard MIL-STD-1913 Picatinny upper receiver. It is the ideal riser for AR-15 owners moving to night vision or for anyone who simply wants a longer, snag-resistant optic platform on a flattop build.
