Control the muzzle, build faster positions, and protect your support hand. The ERGO Hand Stop/Barricade Stop in black anodized aluminum is a compact M-LOK accessory that delivers outsized performance.

Why Choose the ERGO Hand Stop/Barricade Stop (M-LOK)
Dual-Purpose Design: Works as a hand index point for repeatable grip and as a barricade stop to load into cover for steadier shots.
Slim, Low-Profile Footprint: Minimal snag potential and easy clearance in cases, vehicles, and scabbards—ideal for duty or competition rifles.
Machined Aluminum Strength: Hard-anodized aluminum resists impact, heat, and abrasion better than polymer in hard-use environments.
True M-LOK Compatibility: Direct-mounts to any M-LOK slot on modern handguards; no adapters required.
Positive Traction Face: The forward face provides a confident purchase against barriers to manage recoil and muzzle rise during rapid strings.
Ambi-Friendly Placement: Mount forward or rearward on either side of the handguard to match your technique and support-hand length.
How It Improves Your Shooting
Faster Indexing: Your hand finds the same spot every time, improving presentation speed and sight/dot alignment.
Better Recoil Management: Lock your support hand behind the stop to drive the gun flatter in controlled pairs and transitions.
Stable Barricade Work: Load into posts, walls, and ports with the stop as a hard reference point for less wobble and cleaner breaks.
Safety & Heat Buffer: Offers a physical reference to prevent over-travel toward hot gas blocks or suppressor collars on shorter rails.
Ideal Use Cases
3-Gun & Practical Competition: Faster positions on VTAC boards, ports, and awkward props.
Patrol & Training Carbines: Consistent support-hand placement under stress for reliable manipulations.
Home & Property Defense Rifles: Compact control aid that doesn’t crowd lights, lasers, or pressure switches.
SBRs, PCCs & Suppressed Builds: Keeps hands safely indexed on short rails while improving control with added front-end weight.
Installation (M-LOK)
Choose Position: Typically 6–9 o’clock near the front third of your rail for optimal leverage.
Seat Hardware: Insert M-LOK T-nuts through the slot, align the stop, and hand-snug the screws.
Torque to Spec: Tighten to manufacturer-recommended M-LOK torque (≈ 30 in-lb).
Function Check: Confirm nuts have rotated and locked; verify no interference with gas block, barrel nut, or wiring.
Re-Check After Range Day: Verify torque after the first live-fire session and any temperature swings.

Frequently Asked Questions
Q: Will it fit my handguard?
A: If your handguard has M-LOK slots, this stop will mount directly. It does not fit KeyMod or plain Picatinny rails without separate adapters.
Q: Does it add much weight?
A: The low-profile aluminum construction adds minimal weight while delivering excellent rigidity for barricade loading.
Q: Can I mount it at an angle?
A: Yes. Many shooters offset the stop slightly to match personal thumb-over-bore or light-switch ergonomics.
Q: Is it legal for competition?
A: Hand stops are widely permitted, but always check your match rule set (USPSA, 2-Gun, local outlaw) before match day.
