The Primary Arms SLx Flip-To-Side Magnifier Mount is designed to place your magnifier at 1.41 inches above the top of the picatinny rail. Additionally, it includes spacers allowing for a 1.535" and 1.64" centerline height, so you can easily line it up with your optic. It features a low profile design manufactured from 6061-T6 aluminum with two steel alloy crossbolts that apply up to 55 in-lbs or torque to ensure a rock solid mount. This magnifier mount also utilizes a direct bolt system to interface with the magnifier instead of a traditional ring design in order to save weight, increase strength, and eliminates the possibility of the magnifier slipping or twisting in the mount.

  • 6061-T6 Aluminum construction

  • Standard 1.41" optical centerline
  • Includes spacers for 1.535" and 1.64" heights
  • Compatible with direct bolt-on style magnifiers

Height with included spacer and medium sized mounting screws, matches up perfectly with factory mounted MD25 ACSS.

Quality Mount

Attached to a PA SLX 3X Micro Magnifier. Folding mechanism feels snug and secure. Made of quality material. Easy to setup, thanks for the thread locker. Pairs nicely with my PA SLX MD-25.

Happy camper, no complaints! Thanks for quality products, as usual (and for quick shipping)!!

Excellent Flip to Side Mount

by -

This is a very low profile excellent mount. The only reason I gave it 4 stars instead of 5 is because I wish there was a quick detach option. I really believe that is the only thing missing that would make this perfect.

Works Well With 3X Magnifier

Just what you need to flip the magnifier out of the way. Easy to adjust. Mount it as close to the 1X red dot or Cyclops as possible. Highly recommended!

Outstanding design!

I just finished up a 2 day helicopter hog hunting adventure in South Texas, using the product. Perfect performance!

Mounted with 3X magnifier for the 1X Cyclops. Great combo.

I like this mount. It feels beefy, and overbuilt, and it doesn't require a button to flip up or down.

Nice mount but...


So I bought this flip to the side mount for the new micro Slx Pegasus 3x magnifier. I purchased it to sit behind and supplement my Eotech. My problem and not a small one is that the screws provided aren’t long enough to engage the threads of the magnifier. They provide the perfect amount of spacers to center the magnifier to the Eotech but not enough screw length ( in the same box) to mount the magnifier to the mount. Other than that if you can put that aside, it a very good FTTS mount and the Pegasus magnifier is not only crisp and clear the ranging option is spot on and unobtrusive. Just need the proper screws. The mount is robust and snicks solidly into place firmly in battery or to the side.

Great Mount, Great Buying Experience

Primary Arms has earned my #1 spot for gear, parts, and optics. This mount fits perfect on my AR and mates perfectly with red dots and Primary Arms ACSS Cyclops and 3x magnifier. 10 out of 10.
