βš™οΈ Product Details

The Strike Industries TRIBUS Enhanced Castle Nut & End Plate V2 combines an anti-rotation castle nut with an extended end plate that provides three QD sling sockets. The center, left, and right mounting points give users more flexibility when positioning a compatible QD sling, while the extended layout moves the socket area away from the firing-hand web.

Key Features

  • Enhanced anti-rotation castle nut
  • Extended end plate with three QD sling sockets
  • Center, left, and right QD mounting positions
  • Set-screw retention replaces traditional staking
  • Groove supports easier takedown-pin detent spring installation
  • Drop-in installation on compatible carbine receiver extensions
  • Hard-anodized color finish

Compatibility Notes

Strike Industries requires a compatible carbine receiver extension with at least 30 mm / 1.18 in of threaded length. The extended assembly may prevent a stock from reaching its original fully collapsed position. Do not exceed 35 ft-lb when tightening the castle nut.
