Nocpix SLIM-MOUNT-3 Slim Mount-3 QD Picatinny Rail Extended Offset, Fits Slim Thermal Optic
The Nocpix SLIM-MOUNT-3 is a quick-detach Picatinny rail mount engineered to adapt Nocpix SLIM thermal optics to rifles where the factory mount doesn't quite fit the job. If you run a bolt-action, precision rifle, or any platform where a lower sight line or more rearward optic placement improves handling and eye relief, this extended offset mount gives you that flexibility. It's the pragmatic solution when your thermal needs a different home than an AR.
The SLIM-MOUNT-3 uses three indexed positions along the rail, so you can dial in the eye relief that works best for your rifle's geometry and your shooting style. Move the optic forward or back to find the sweet spot—whether you're behind a magnum bolt gun with a tight cheek weld or a precision .308 where you want the glass sitting back a bit. That positioning control is especially valuable with thermal optics, where eye relief tolerance is less forgiving than with traditional glass.
Built as a direct replacement for the standard SLIM factory mount, the SLIM-MOUNT-3 maintains full compatibility with Nocpix SLIM thermal optics while offering the extended reach and lower height over bore you need on non-AR platforms. The quick-detach design keeps your workflow simple—swap mounts without losing zero or wrestling with your optic setup.
