Need a compact hand stop for a Picatinny rail? Check out the Arisaka HS-P

When I built our a pistol with recoil, I worry about my hand slipping off the handguard and going in front of the muzzle. I recently bought a Stribog 10mm and that was running through my mind – so I started digging for hand stops that could mount on a picatinny rail.

I should point out I don’t like angled fore grips (AFGs) or anything that incorporates that design aspect. I like the bottom of the handguard to be flat. I also like hand stops that are small from an aesthetics perspective plus I don’t want the ATF, or whomever, arguing that I actually have a vertical grip which is illegal on a pistol.

I ran across an ad for Arisaka Defense’s HS-P handstop. It mounts on rail though I couldn’t quite figure out how from the website photos. Because I’ve had good luck with Arisaka products in the past, I gambled and ordered one. Guess what? I really like it and figured a quick post might be of interest to others.

So the HS-P is CNC machined from 6061-T651 aluminum and MIL-A-8625 Type III hard coat anodized.

The secret sauce that makes this so cool is that grey aluminum recoil lug. There is a screw attached that you can’t see that raises or lowers it into whatever Picatinny rail slot you want locking it in place. Simple and slick!

The front has slots cut into it. I suppose that could help if you want to use it on a barrier.

On the bottom is the hole for the screw. Use a 7/64″ allen key to tighten (push the lug up) or loosen (lower the lug down). Torque is 15 in/lbs – please note that is inch/pounds and not foot/pounds.

In this photo, you can see the retracted recoil lug. I then just slid the HS-P onto the handguard’s rail to where I wanted it.

I slid the HS-P on and then used my closes allen set with a 7/64 key to raise the lug into position. I brought it up firm but not crazy tight – I didn’t have a long enough key for my torquing screw driver handy (meaning it is “temporary misplaced”) so I opted for ballpark tight. They don’t include a 7/74″ allen key by the way. It doesn’t bother me because I have a bunch. Also, often times the “free” keys that come with something aren’t very good – I’ve torn things up many times in the past trying to use marvel mystery metal included keys so I don’t do it any longer.

The HS-P is rock solid.

Summary

It you are looking for a solid small hand stop that mounts on a rail, the Arisaka HS-P is great. I have no reservations recommending it.

Yes, I actually bought this. I was not paid to write this.

Note, I have to buy all of my parts – nothing here was paid for by sponsors, etc. I do make a small amount if you click on an ad and buy something but that is it. You’re getting my real opinion on stuff.
