The Mossberg M-403 Shotgun Interface system is a simple M1913 picatinny interface that offers a solid mounting platform for a variety lights and lasers. CNC machined from aircraft grade 6061-T6 billet aluminum and given a Mil-Spec (MIL-A-8625) Type III hard anodize, these M1913 picatinny interfaces are designed to accept any accessory built for the military rail specification. |
| One of our primary design criteria is simple installation with hand tools. There is no need for an armorer to strip down the weapon to install these mounts. They bolt onto the weapon in a matter of minutes. An innovative clamping system keeps the mount in place under the most extreme conditions. |
