RailScales engineers designed this Karve Handstop to fit everyone. Thanks to their innovative COG Multi-Mount System, no matter which rail system you have or how you like to hold your weapon the RailScales Karve will work for you.

It doesn't matter which rail system you use, it’s in there like bam!


Top Notch Product for A Top-Notch Client

The RailScales Handstop is machined from solid Billet Aluminum. That makes it lightweight, and tougher than nails. Its low profile beneath your rail won’t hang up on everything. I don’t mean to but sometimes even I forget to strap something down. The RailScales Karve wears a tough anodized finish you’re going to love under your rail. To go with your current handguard finish, the Karve Handstop offers you three color options. You can get it in Carbon Black, Orbital Grey, or Terra Bronze. So, pick one, or get all three.
