Tribus FDE castle nut set
Reviewed on February 6, 2026Verified with Build

Strikes Tribus combo in FDE matches my Magpul MOE grip and stock nicely. The castle nut has the bigger wrench cutouts which are easier to torque properly. End plate sits flush against the receiver, no gap. Staking holes are positioned correctly for AR15 wrench access.
