Most Helpful Positive Review Team Warne mount
Extremely well made, supports my red dot perfectly. adding a riser to the mount puts it in perfect view without changing where your cheek is on the buttstock. I recommend adding lock tight to the screw to ensure it stays secured.

Great Offset Mount

by TattooedAssassin, Verified Owner from SC, United States Written on January 13, 2025
Works as described, durable, easy to install. If you have a scope and have room on your rail, get one.

Works well

by TattooedAssassin, Verified Owner from SC, United States Written on December 31, 2022
Currently set up on my AR-10 with a CT Red dot. Does the job well and holds solid if installed properly. I would also recommend making sure that any hardware you add has the mounting screws on the outside of this mount, so your screws aren't covered by a scope or other hardware.

Bummer, man

by Jack, Verified Owner from CA, United States Written on October 2, 2020
Bought these because I own two Warne mounts that are excellent. These are not. Troy fixed battle sights don't fit at all. I sprayed dry lube and used anti seize gun grease to try to slide the sight over the rail but the angle is too steep or the Troy is too fat. Either way I'm pretty disgusted. The package says accommodates most picatinny accessories. Yeah, except the #1 manufacturer of picatinny sights. Seriously, I've been buying AR junk for a long time and I've never had a part not fit as badly as these don't fit. Buying JP.

Exactly what I was looking for

by Chief, Verified Owner from AZ, United States Written on July 26, 2020
Needed to clear my flip up Magpul backup sights on AR15 around ATN X-Sight HD. And they do. The X-sight is large and bulky and I took a chance and it paid off. The 45 degree mounts are very well made and fit snug. Can't really ask for more and is what I expected. This is my second Warne purchase, the first being a RAMP for for my AR with a Leupold scope. So I new the quality would be there.
Pros:
  • quality and fit
Cons:
  • None
Best Used for:
  • back up sights
  • Flip up sights
Would recommend: Yes

Perfect 45 degree adapter

by Al Heffe, Verified Owner from NC, United States Written on January 6, 2020
Needed adequate clearance for a back up red dot sight when using a FLIR PTS233 on my rail equipped STG-77. A number of other major manufacture's 45 degree side mounts did not allow enough space between the rail on the STG-77 and red dot optic to clear the thermal scope that sits one slot behind. Finish on the mount is stellar. Warne's top drawer quality and Optics Planet amazing shipping and service makes for a happy day patrolling at the compound.
Pros:
  • Quality
  • Esthetics
Cons:
  • None
Best Used for:
  • Back up optics in limited space
Would recommend: Yes

45 degree mount

by terry, Verified Owner from PA, United States Written on September 19, 2018
I used this on an an ar15 using a Burris fast fire 2. I had no issues with installation or getting the optic zeroed. Fit and finish is good. It makes for a fairly low profile setup. I would recommend.

Beautiful and Strong

by Steven, from IN, United States Written on July 18, 2018
This is really a good looking little piece of aluminum. Plus, with the red contrasting with the Aero Precision Air Force builder's set it's on... super cool. Fit and finish are fantastic. And, OP has always had quick shipping and great service!
