Holosun RMLT Red Rail Mounted Laser 1mW - 5mW with Grade 5 Titanium Housing
The Holosun RML is a compact rail-mounted laser that keeps things simple and lightweight. It uses a durable polymer housing to cut down weight while still staying tough enough for recoil and daily use. You get a clean visible red laser (with adjustable 1mW / 5mW output depending on the model), ambidextrous controls, and easy windage/elevation adjustment so zeroing is straightforward. It mounts directly to a Picatinny rail and is small enough to pair with a light or optic without taking up much space. It’s basically a no-frills, budget-friendly aiming laser for quick target indexing in close-range setups.
