Product Description

The Fortis Manufacturing Lightweight Enhanced (LE) K1 Castle Nut & End Plate System is engineered to help prevent your AR-15 castle nut from backing out without the need for staking. The K1 lockdown system uses a tapered castle nut that seats and seals onto the end plate for an ultra-precision, snug fit. Built from 7075-T6 aircraft-grade aluminum and finished in anodized black/gray, this robust, minimalist design eliminates ratcheting mechanisms and set screws while keeping weight extremely low. A 360° rotational quick-detach (QD) socket interface adds sling-mount versatility for hard-use setups.

Product Highlights

  • K1 tapered castle nut design helps lock in place without staking the end plate
  • Lightweight Enhanced (LE) system keeps total weight to approximately 0.59 oz (16.8 g)
  • 7075-T6 aircraft-grade aluminum construction for strength with minimal bulk
  • 360° rotational QD socket interface for flexible sling attachment positioning
  • No set screws and no ratcheting mechanism for a clean, streamlined installation
