Holosun RML-GR Rail Mounted Green Laser Sight Black

The Holosun RML-GR is a compact rail-mounted laser sight designed for handguns, pistol-caliber carbines, and short-barrel rifles, delivering a vivid 520nm green aiming point with a class 3R output for fast, daylight-visible target acquisition. The green laser is significantly easier to pick up in bright conditions than a comparable red unit, making the RML-GR a natural fit for duty, defensive, and competition use.

Built around a rugged polymer housing with a matte black finish, the RML-GR is rated IP68 waterproof and dustproof and is tested to withstand 2000G of recoil, so it holds zero on everything from subcompact 9mm pistols to 5.56 carbines. The unit weighs just 1.30 oz and measures a compact 1.97 in x 1.18 in x 0.9 in, allowing it to sit low and flush on a pistol dust cover or handguard without adding bulk or snagging on the holster. It is engineered to remain compatible with most weapon-light holsters when mounted alongside an existing pistol light.

The RML-GR runs on a single CR1/3N battery (included) for approximately 100 minutes of continuous runtime, and the battery is user-replaceable without removing the laser from the host firearm. Activation is handled through ambidextrous top-mounted buttons that work equally well for right- and left-handed shooters. Tactile windage and elevation adjusters deliver positive click-by-click feedback at 4 MOA per click for precise zeroing, and the unit ships with adapter keys, a T10 L-key, and a lens cloth for installation and maintenance.

Featuring a low-profile universal rail mount, the Holosun RML-GR clamps directly to any standard Picatinny or Glock-pattern rail and is an ideal co-witness or offset aiming solution for modern defensive pistols and AR-platform rifles.
