Product Description

The Patent Pending Arisaka Hand Stop is a continuation of the low profile, minimal control accessories. The primary goal of this accessory is to aid the user in pulling their rifle into their shoulder, enhancing control and recoil mitigation. The Hand Stop can also be used as a barricade stop, or reversed and placed at the front of the handguard to prevent the support hand from slipping off the end. The size and profile were designed to fit a wide variety of hands without being too large to get in the way.

The Arisaka Hand Stop Picatinny uses a unique recoil lug that extends from inside the part, providing a secure, rattle free lockup. The recoil lug and patched mating screw are captured and cannot fall out when the Hand Stop is removed from the Picatinny rail. A rotation direction indication is CNC engraved onto the part to aid in tightening or loosening the recoil lug. A 7/64″ Allen wrench is required for installation, with a maximum torque specification of 15 inch lbs.

Awesome product

The feel and the look of Arisaka Defense Picatinny Handstop is awesome. It just goes with your finger while doing C clamp on the handguard. And you can also manipulate your hand position and this handstop will support you. I’m glad I bought this item!!!

Ergonmic and great fit for what I want

I was unsure of the size because I’ve only ever seen it in pics. I usually have to see it up close to get a good grasp as to what I’m getting into. I have used many different stops/grips. What I’ve found is that I change tools based on how I’m going to use something or when I learn new techniques. So my use of stops/grips continually will evolve as I get new information and if it fits for what I want. That being said, this stop is top notch quality. I believe RailScales to be the Gucci of Gucci when it comes to stops and grips but this Arisaka stop def surprised me by how solid it is and the textures of the forward aspect of the stop. It’s very thought out and designed to give maximum dexterity to the end user. Whoever thought this up def listened to the end user. I honestly don’t have any complaints. It’s a great accessory to add if what you’re trying to do is clear rail space allowing you to grip your pic rail better. I guess I could’ve just said just that but I felt the need to give a little dissertation on it,
