The M203 Quadrant Sight A2/A1 Mounted is a classic aiming system purpose-built for shooters running 40mm grenade launchers on AR-platform rifles. If you're operating an M203 or compatible underslung launcher, this quadrant sight gives you a proven, field-tested sighting solution that's been relied on by military and law enforcement for decades. The A2/A1 mounting configuration integrates directly onto your rifle's carry handle or receiver, keeping your sight picture consistent and your profile compact.
Quadrant sights work differently than conventional optics—they use a graduated elevation system calibrated for the ballistic arc of 40mm rounds at various distances, letting you dial in holdovers quickly in the field. This design keeps the sight simple, durable, and free from batteries or electronics that might fail when you need them most. Whether you're at the range, on a training evolution, or in a duty context, the straightforward mechanical adjustment and robust construction mean your sight stays where you set it.
LMT Defense's reputation for precision manufacturing and mil-spec reliability carries through to this component. The A2/A1 mount fits standard carry handle and receiver-mounted setups, so integration into your existing rifle is straightforward. This is a no-nonsense piece of kit for anyone serious about their M203 platform.
This sight is configured for A2/A1 mounting, which includes standard AR carry handle and receiver-mounted platforms compatible with these interfaces.
A quadrant sight uses graduated elevation marks calibrated to the ballistic arc of 40mm rounds at different ranges. You dial the elevation knob to your target distance, and the sight picture accounts for the round's drop, allowing you to aim directly at the target without manual holdover calculations.
Yes. The M203 Quadrant Sight works for training, qualification, and practical range applications wherever you're running an M203 or compatible launcher on an AR with A2/A1 mounting.
