Questions & Answers
Will a vortex viper fit this rail mount? Manufacturer Answer

The Viper will not fit this mount.

by Vortex, Manufacturer, August 28, 2025
Will this mount work with a Ruger mark 2 and a viper? Expert Answer

This mount works with any 3/8" rail for firearms that don't have a weaver or picatinny rail. This would not work for the Vortex Viper as it is for the Razor red dot sight, not a Viper riflescope.

Vortex Razor Reflex Sight Low Profile by denisk113, Verified Owner, August 23, 2017
Excellent quality, just as expected from Vortex. Perfect match for the Razor sight I mounted on my Henry Mare's Leg for late night pest control. Makes for a deadly combination when it's too dark to see the sights.

Product Info for Vortex Razor Reflex Sight Low Profile 3/8in Rail Mount

Vortex Razor Reflex Sight Low 3/8in Rail Mount MT-5107 vastly expands the possibilities of your Razor red dot sight. Though the Vortex Razor Reflex Sight comes packaged with a sturdy Picatinny rail, you might not own a firearm that's equipped with a Picatinny rail, so the sight is useless without the appropriate scope mount. Fortunately, Vortex Optics manufactures a wide range of rail adapters for the Razor reflex sight; this particular model can mount the sight to any 3/8" rail, whether it's on a rifle, shotgun, or pistol. The Vortex Razor Red Dot Low Profile 3/8" Rail Mount has a low profile construction that won't snag or get in the way of your other equipment and attachments. If you have a firearm with a specialized 3/8 inch base, this Vortex scope mount is a necessity for mounting the Razor sight. Add precision red dot accuracy to your 3/8" base-equipped weapon with the Vortex Razor Reflex Low Profile 3/8 Inch Sight Mount.image
