Product Description

The Fortis K1 Lightweight Enhanced (LE) Castle Nut & End Plate System is engineered to help keep your AR-style receiver extension assembly secure without the traditional need to stake the end plate. The K1 system uses a tapered castle nut designed to seat and seal tightly onto the end plate for a robust lockup that resists backing out. Built from 7075-T6 aircraft-grade aluminum and finished in anodized OD Green/Black, this castle nut and end plate combo also integrates a 360-degree rotating Quick Detach socket for sling attachment—all while keeping weight to an ultra-light 0.59 oz (16.8 g).

Product Highlights

  • K1 tapered castle nut design seats and seals to help prevent loosening without staking
  • Ultra-lightweight system: 0.59 oz (16.8 g) total
  • 7075-T6 aircraft-grade aluminum construction for high strength with low weight
  • Integrated 360-degree rotating Quick Detach socket for sling compatibility
  • No set screws or ratcheting system required
