The LMT Defense M203 Quadrant Sight Rail Mounted is a purpose-built aiming solution for shooters running the M203 grenade launcher under their rifle platform. This rail-mounted variant positions the sight for quick target acquisition and adjustment, making it an essential accessory for those operating M203-equipped AR platforms or legacy military-spec rifles in training, reenactment, or authorized military use.
Quadrant sights offer a proven mechanical aiming system that doesn't depend on electronics or batteries—a straightforward approach to distance estimation and hold-over on indirect-fire weapons. The rail-mount configuration integrates seamlessly with modern receiver setups, letting you zero and adjust without replacing your existing optics or rail infrastructure.
LMT Defense manufactures this sight to mil-spec durability standards, meaning it's built to handle the recoil and field conditions that come with centerfire rifle use. Whether you're training on legacy platforms or maintaining a specialized AR build, the quadrant sight delivers the ruggedness and repeatability you need for consistent performance downrange.

| Product | M203 Quadrant Sight |
| Mount Type | Rail Mounted |
This sight is designed for rifles equipped with M203 grenade launchers and modern Picatinny rail systems. Compatibility depends on your specific platform's rail configuration and M203 setup. Verify your rifle's rail compatibility before ordering.
No. The M203 Quadrant Sight is a mechanical, battery-free aiming system. It operates independently of electronics, making it reliable in field conditions without power requirements.
The rail-mounted design allows integration with your existing rail system, but co-witnessing depends on your rifle's rail configuration, optic height, and sight placement. Plan your setup around your specific platform before purchase.
