Closest thing to welding an rmr to a shotgun.... - Scalarworks SYNC Trijicon RMR Standalione Mount

This mount is meticulously designed and flawlessly machined. Installation was a breeze. There are 3 sets of screws. One to attach the RMR to the mount. One to insert in the middle two screws of the receiver to act as recoil lugs by slotting in the bottom of the mount. One set for mounting the mount to the receiver. They were kind enough to include the correct bit and provide torque information. The RMR is rock solid and mounted low to the bore. I couldn't be happier.

I mounted this to a Stoeger M3K which has the same receiver design as the M3000. Hole spacing was perfect.
