AR15 Riser Mount with Quick Release

The AR15 Riser Mount with a quick release lever is designed for mounting the Razor red dot sight onto a flattop style AR-15 rifle as the primary optic. When used in conjunction with the Picatinny clamp included with the Razor, this mount positions the red dot of the Razor in the lower third of the field of view when co-witnessed with the iron sights.

Note
The AR15 Riser Mount provides a rise .6 inches (15.3mm) above the base surface. Weighs 3 ounces. Made with pride in the U.S.A.

  • Provides lower 1/3 co-witness with the Razor red dot.
  • Provides absolute co-witness with the SPARC red dot.

AUTO LOCK LEVER SYSTEM

The AR15 Riser Mount features the Auto Lock Lever System and has the following advantages:

  • Does not require proprietary tools for adjustment.
  • Can be adjusted with your finger or a flat blade screwdriver.
  • Lever can be configured to lock to the front or the rear.
  • Superior clamping surface ensures maximum rail engagement.

Materials and Construction

The mount is precision Computer Numeric Controlled (CNC) machined from a solid block of aluminum and finished in a hard coat anodize for a rock-hard, lasting finish.

  • Precision machined from 6061 T6 aluminum.
  • Hard coat Type 3 Mil-Spec anodized for a lifetime of performance.
  • Fully adjustable to fit both in and out of spec rail systems.

Rated 5 out of 5 by from Rock solid mount I use this to mount my Razor red dot to co-witness flip up iron sights on an AR platform. The rifle is used in a LE capacity and I wouldn't use anything on that rifle that I don't trust to work 100% of the time. This mount is solid, I like it a lot. The quick release is nice, and it has a safety mechanism that prevents it from being released accidentally.

Rated 5 out of 5 by from Perfect as usual. I needed to raise the scope a bit. The staff at vortex recommended the riser and installed it. It is now perfect! Why would you go anywhere else. Perfect products and staff. Thankyou Votex

Since there is really no industry standard for lower 1/3 cowitness, what is the optical axis in relation to bore or your definition of lower 1/3 cowitness?  Thank you

Asked by: Bub KY
We would be looking at 37 mm above the rail.

Will this mount work with spitfire 3x?

Asked by: Mike
Yes, it can be mounted on this riser. If you are looking for a quick release mount however, you can find one designed for the Spitfire 3x here: https://www.americandefensemanufacturing.com/browse/category/mounts/opticmounts/vortexopticmounts/.

If using this riser mount between a Vortex Venom and an AR-15, would the co-witness be absolute or lower 1/3?

Asked by: Doug
The Venom on this riser will be higher than absolute co-witness but lower than standard lower 1/3 co-witness height. If you are looking for lower 1/3 co-witness height with your Venom you will want this riser: http://www.vortexoptics.com/product/red-dot-mount-riser-qr

Will this mount work with the VMX-3T magnifier?

Asked by: Billsfan808
The VMX-3T will mount on this rail, however it will make it extremely high and would not be practical.

Thanks for the reply about the mount but I didn't get an answer to my question of what height is the rise, 1/2" or something else, please advise.

Asked by: Brownie123
This mount is .6" or 15.5 mm tall.
