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. 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!

I have a Colt 6940. I would like to get a Strike Eagle 1x8 with a CM 404 mount. Will this setup clear the Matech rear sight on my rifle ?

Asked by: Star Gazer
The eyepiece will be 0.6" off of the rail, if your sight folds lower than that it should clear.

I have a Colt AR Model 6940 flat top receiver with folding iron sights. I want to mount a Strike Eagle 1-6 on this platform and be able to use the iron sights while the scope is attached. Do you offer mounts to facilitate?

Asked by: Joe W
If you want to be able to use your iron sights while the scope is attached you would need to use a set of 45 degree offset iron sights or use a QR cantilever mount to take the scope off.

I believe the CM-403 (Vortex Precision QR Extended Cantilever 30mm Bobro mount) was manufactured by Bobro for Vortex. Is the CM-404 also manufactured Bobro?

Asked by: DFW Spartan
The CM-404 is manufactured by American Defense Manufacturing.

I've got a DPMS LR.308 and a Crossfire II 6-24x50. Would you recommend this mount or a different one? I'm concerned about the height being too high. 

Asked by: Dmcortez99
This mount will work great on your rifle. Our cantilever mounts are designed to be the proper height for use on AR rifles.

What would be the best mount for a Crossfire 2 1-4x24 on a Colt Commando AR short barreled?

Asked by: Corey
Any one of our cantilever mounts would give you proper mounting height on your AR without a carry handle. If your AR has a carry handle, you will need a picatinny rail on top of the handle and a set of low height rings.

I just purchased a PST gen II 3-15x44 for my M1A scout which has an ARMS #18 mount. I would prefer a QD mount if possible. Would the precision QR Extended Cantilever Mount be a good choice? Will it also return to zero after removal?

Asked by: djboel
This mount would go on your rifle without any trouble, but it would place your scope very high off the gun and you would need a cheek riser to keep a good cheek weld while being able to see through the scope.

I have a POF Warhog .308 and recently purchased the Razor HD Gen1. What combination would you recommend in regards to scope mounts. 

Asked by: Cody
I recommend our Precision Extended Cantilever mount, the 35 mm 20 MOA version would work great for your setup.

Would this mount work with a viper hs 2.5-10 on a tactical solutions x ring rifle?

Asked by: Bsummitt
This mount will be very high for your setup, I recommend a set of Precision Matched 30 mm rings in 0.87" height.
