Expand your magazine capacity with a Nordic Components extension nut and tube kit.
The SX-model nut is compatible with the following 12 gauge 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
Any magazine dimples or spring retaining devices will need to be smoothed or removed to allow proper function.
