Holosun RML Red Rail Mounted Laser 1mW - 5mW with Polymer Housing
The Holosun RML Red Rail Mounted Laser is a small, lightweight aiming laser built for pistols or compact rail setups. It keeps things simple with a visible red laser that can switch between low (1mW) and high (5mW) output, so you can balance visibility and battery life depending on use. The polymer housing helps keep weight down while still being tough enough for recoil and daily handling, and it mounts directly to a standard Picatinny rail. You also get ambidextrous controls, easy windage/elevation adjustment for zeroing, and a compact profile that pairs well with lights or other rail accessories. It’s basically a no-frills, budget-friendly laser for quick target indexing at close range.
