TacFire® Gen 2 1-Slot M-LOK Handstop - Lightweight Aircraft Aluminum, Low-Profile Ergonomic Design, Steel M-LOK Mounting Hardware, Anodized Matte Black Finish - MAR133-G2 / 686294505690
Product Description
Controlling muzzle rise and maintaining a consistent hand position on modern free-float handguards is key to fast, accurate follow-up shots. Bulky vertical foregrips add unnecessary weight and snag on gear, while shooting a slick rail can cause your support hand to slip forward toward a hot barrel or muzzle device. The **TacFire® Gen 2 1-Slot M-LOK Handstop (MAR133-G2 / 686294505690)** fixes these front-end control challenges, delivering a ultra-compact, low-profile reference point that mounts directly to any M-LOK handguard rail slot.
Machined from lightweight 6061-T6 aircraft-grade aluminum, the Gen 2 MAR133-G2 handstop features an updated ergonomic curved profile. You can mount it facing backward as a rearward handstop to pull the rifle firmly into your shoulder pocket, or face it forward as a forward barrier stop to prevent your hand from slipping past the end of short AR pistols or SBR handguards. Finished with a tough matte black anodizing, this single-slot accessory adds minimal weight while giving you a solid, repeatable grip index every time you bring your rifle up.
Designed for universal fitment across all standard M-LOK handguards, this compact aluminum handstop provides positive front-end weapon control right off your workbench.
*Armorer Bench Notes & Real-World Staging Guidance: The TacFire MAR133-G2 handstop comes complete with M-LOK steel T-nuts and mounting screws. HANDGUARD FITMENT MATRIX: Fits any standard **M-LOK handguard slot** (requires only 1 open M-LOK slot). *Orientation Note:* The curved design allows bidirectional installation depending on whether you prefer a thumb-over-bore pull stop or a forward safety barrier stop. Workbench Setup Steps: 1. Ensure your firearm is completely clear of ammunition and verified safe before installation. 2. Thread the included steel screw and M-LOK T-nut loosely through the handstop body. 3. Insert the T-nut horizontally into your chosen M-LOK rail slot. 4. Apply gentle outward pressure while tightening the screw with an Allen wrench so the T-nut rotates 90 degrees into the locking position inside the handguard. 5. Torque snug (approx. 25-30 in-lbs) and verify zero wobble before range testing.*
