The Strike Industries TRIBUS Enhanced Castle Nut & End Plate is a drop-in AR-pattern upgrade that replaces the standard castle nut and end plate with an extended platform designed for easier sling setup and improved retention. Its geometry positions QD mounting points to keep them clear of the primary hand during manipulation, while the anti-rotation castle nut set screw helps prevent backing out under use.

Black anodized finish for durable, corrosion-resistant use
3 QD sling mounting points for flexible sling routing (including left and right sides)
Anti-rotation castle nut feature with set screw helps keep the nut secured
