Precision QR Extended Cantilever Mount

This quick-release cantilever mount is designed for mounting telescopic sights with 30mm tubes onto a flattop style AR-15 rifle. The offset of this cantilever mount positions the scope in a forward location, providing correct eye relief and head placement when used on an AR-15.

Materials and Construction

The Precision Optic Mount is precision CNC machined from a block of 6061 T6 aluminum and finished in hard coat type 3 mil-spec anodized black for a rock hard lasting finish.

  • Precision machined from 6061 T6 aluminum.
  • Hard coat Type 3 Mil-Spec anodized for a lifetime of performance.

Note
This mount positions the center of the riflescope tube at a height of 1.45 inches (37 mm) from the top surface of the Picatinny base. Ring screw bit size is 9/64” hex head. Weighs 8.9 ounces. Made with pride in the U.S.A.

Rated 5 out of 5 by from Unbelieveable! I have this mount on a custom AR with a Viper PST 4-16x50 FFP scope. Unbelievable how well this setup works for tactical use or varmints... which are sometimes one in the same. Repeatability is perfect and the scope is off and back on quickly and securely when needed for maintenance or to use open sights. These mounts are a bargain and they're rock solid. Just ordered another one for a different gun.

Rated 5 out of 5 by from Rock solid mount! I used this mount to attach a Vortex Viper PST 6-24X50 FFP to a Ruger Precision Rifle. Probably didnt need a QR mount for this, however, it is super easy to install and it holds tight to the base. What i like about this mount is that there is no need for lapping the rings. This mount is rock solid and the QR is super easy to adjust.

Rated 5 out of 5 by from Thanks Again VTX! I paired this QR Mount with the Eagle 1-8X on my Scionics Patrol2 and Function/Fit is perfect. Plenty of adjustment for eye relief. The intent of the QR for me was to go lighter if I needed to or quickly swap to Red Dot and it fits the need perfect. Scope-Ring alignment was never easier and Certainly no Lapping Rqrd. Also recently upgraded from the Eagle 1-6x to the Eagle 1-8x. That extra little bit makes a big difference with my eyes approaching 48 years old, I also dig the new BDC2 reticle. Previously I had a 3" Extended NON QR 30mm mount (not a Vortex) with my Eagle 1-6x, I found this pushed the scope forward a little too much, as I like running my 45 Deg. iron site behind the mount. This 2" Extended mount seems to fit Perfecto! Thanks again for an excellent product!

Rated 5 out of 5 by from AR 10 Put these mounts on my AR10 6.5 creedmoor with a 5 x 25 x 50 gen 2 scope and really like the ease of removal to clean the gun, little pricey but still would recommend.

Do you recommend lapping these rings

Asked by: Joe gott
Thanks for the question! There is actually no need to lap these rings!

I have read your answer that you recommend going with 30mm Precision Matched Rings 1.45" for Ruger Precision.  The new GEN3 rifle specifically has a lower profile Handguard for better scope clearance. Can a lower ring be used? 

Asked by: Jordan
Thanks for the question! You could use the 1.26" inch height or the 1.45" inch height.

Can I run this with strike eagle 1-8 scope and magpul rear flip ups?

Asked by: Rojo
Yes you can run that mount with the Strike Eagle 1-8. You're unable to run iron sights through a variable optic as they will not be accurate. I recommend using a 45 degree offset mount - http://vortexoptics.com/product/red-dot-mount-45

Would this mount and the Razor HD AMG work well on a Ruger Precision?

Asked by: Jason
Thanks for reaching out! This would work fine for your RPR! However, the cantilever mount is going to push the optic forward. I generally recommend going with a set of our 30 mm Precision Matched Rings 1.45" inch height for that setup.

Using this mount on a dpms style AR10 what would be the scope height over bore? when i measured it ranged from 2.6-2.9in? is there a more exact answer?

Asked by: russell
Unfortunately I don't have a DPMS AR 10 to measure, but I can tell you that the height from the top of the picatinny rail to the center of the scope tube in that mount is 1.45". If you just measure from the top of the rail to the center of the bore and add that to 1.45" you should have a solid measurement.
