When you start mounting optics on your ARs, it’s easy to wind up spending a lot of money on different toys. Now, I enjoy big boy toys as much as the next person, but I really don’t need a drawer full of unused mounts to look at. Why not consolidate, spend less, and get something versatile when you decide to get a new riser mount.

Specifically Different

Unlike many other Picatinny rail riser mounts Strike Industries designed their new R.EX Picatinny riser mount to adapt to multiple mounting options. Although this riser mount is custom made to hold a R.EX type protective mount, the Picatinny rail riser will easily accommodate many other optics that are meant to be mounted on Picatinny sections. This game-changing Picatinny riser mount is machined to perfection and solidly hangs onto your weapon, keeping your optics securely in place.

A Picatinny Rail Riser That Is Adaptable to You

Depending on your preference of shooting style, adjusting the co-witness height of your optics is a just a spacer away. Strike Industries produce top-quality parts for shooters to run with, they’re quality parts that are meant to be used. Certainly, this riser mount is available in several different color choices to give your weapon a little pizazz, who says that you can’t look good while delivering the goods. So, you can spend a wad of cash on a box full of different mounts, or you can save money and get one mount from Strike Industries that will give you a number of options. Make a move to the low-profile, light-weight mount from Strike Industries and strike the wasted money out of your budget.
