The Nordic Components SX-12 Winchester/FN 12GA Shotgun Barrel Nut (NUT-SX-12-00) allows for the installation of an MXT extension tube kit and replaces the factory magazine cap.
Compatible 12GA Shotguns:
- Winchester SX2, SX3, and SX4
- FN SLP and SLP Mk. 1
- Browning Gold – Note: Due to issues with excessive magazine spring tension, we do not recommend an extension longer than +4 for this shotgun.
- Browning Silver
Note: Magazine dimples or spring retaining devices, if present, need to be smoothed or removed to allow proper function.
