Arisaka Defense M-LOK Aluminum Hand Stop – Precision Control & Lightweight Durability

The Arisaka Defense M-LOK aluminum hand stop is a low-profile grip accessory designed to improve control and consistency on modern tactical and precision rifles. Built for shooters who want better support hand positioning without unnecessary bulk, this hand stop works across multiple shooting applications—from competition and training to field use. Its compact footprint fits a wide range of hand sizes while staying out of the way during weapon manipulation.

The primary function is to help you drive your rifle firmly into your shoulder, which enhances recoil management and shot-to-shot repeatability. Many shooters also use it as a barricade stop when shooting from barriers or hard cover. If you need it, the hand stop can be reversed and mounted at the front of your handguard to prevent your support hand from slipping off the end during aggressive shooting or movement. That versatility—multiple positions, one component—makes it practical for hunters, competition shooters, and anyone running a modern AR-platform rifle.

Machined from aluminum and finished for durability, the hand stop weighs less than an ounce, so it won't add noticeable heft to your setup. It mounts directly to M-LOK slots using included hardware: two M-LOK nuts and two Torx button head screws. Installation is straightforward and requires no gunsmithing. Arisaka Defense manufactures this accessory in the USA, backing the design philosophy that effective rifle control comes from smart geometry, not oversized components.
