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 Red Dot mount I have a KEL-TEC Sub 2000 9mm a lesser mount kept coming loose on me. This mount was the Best I have ever spent. Went to the range today 200 rounds as fast as could load the Glock 17 - 31 round magazine. Red Dot never moved. I'm telling anybody that will listen. Do not waist your money on any other mount.

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

Does this riser work with a Sparc AR? Not like a picatinny sadwich but mounted instead of the original picatinny mount?

Asked by: Petter
Thanks for the question! This riser requires a Picatinny rail to mount to, so you will not be able to use this in place of one if I am understanding your question correctly. If this isn't what you mean, please give us a call at 800-426-0048 ext. 5 and we can help you out!

I have a Ruger AR 556, and I would like to use the VENOM® RED DOT. My rifle has the fixed front site/gas block. Do you manufacture an adapter for the above site to lift it up far enough to use?

Asked by: Seadub01
Thanks for the question! You will probably have your sight in your field of view even when lifting it up. However, we have two options for you: http://www.vortexoptics.com/product/red-dot-mount-riser-qr http://www.vortexoptics.com/product/razor-red-dot-ar15-mount-with-quick-release-lever

Will this QR fit a Spitfire AR? Or can you recommend a QR for my optic?

Asked by: Rafi83
Thanks for the question! There is not currently a quick release option that is suitable for the Spitfire AR.

Will this mount, with the low mount on the Crossfire Red Dot, achieve an absolute co-witness?

Asked by: mjc2122
No, it will be too low for an absolute co-witness.

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.
