The Arisaka Defense Hand Stop in Picatinny Black (Arisaka Defense part no. HS-P) brings the same low-profile control shape as Arisaka’s M-LOK Hand Stop to a Picatinny rail mount. Arisaka Defense built this version around a recoil lug that extends from inside the part for a secure, rattle-free lockup on a Picatinny rail, with the recoil lug and its mating screw captured so neither can fall out once the hand stop is removed. A rotation direction indicator is CNC engraved onto the part to make tightening or loosening straightforward. Installation takes a 7/64-inch Allen wrench, torqued to about 15 in-lbs.
