Up for sale is an authentic, tank-built SureFire M900 Series Vertical Foregrip WeaponLight. This is the iconic peak-GWOT setup used heavily throughout the early 2000s on US Navy SEAL MK18 Mod 0s, M4A1 SOPMOD Block 1s, and CQBR builds.

Unlike stock legacy models that burn through batteries with dim incandescent output, this unit has been upgraded with a modern LED drop-in conversion. You get all the classic retro aesthetics and bombproof aluminum/polymer construction, but with drastically improved lumen output, clearer beam throw, and modern battery efficiency.

Key Features & Specs:

Upgraded LED Bezel: High-output LED conversion installed (significantly brighter and cooler-running than the original MN10/MN11 incandescent bulbs).

Rail Compatibility: Mounts rock-solid to any standard MIL-STD-1913 Picatinny rail.

Integrated Controls: Dual momentary pressure pads on the grip sides, rear thumb switch for secondary navigation LEDs, and a master rotary disable switch at the tail base to prevent NDs/battery drain in transit.

Power: Runs on (3) standard CR123A batteries.

Condition: Used with clean, honest cosmetic wear on the outer bezel and housing. Solid, fully operational, and ready to mount.

Ideal for finishing off a period-correct MK18 Mod 0 / clone build, retro shorty, or heavy-duty home defense setup without sacrificing modern light performance.

Price: $200 Cash, Venmo, PayPal. Trades Considered.
