Tribus red castle nut set
Reviewed on April 28, 2026Verified with Build

Strike Tribus enhanced castle nut and end plate in red is a bold accent against a black receiver. Larger wrench notches make torquing easier. End plate has integrated QD recessed into the body. Anti-rotation flange seats positively.
