Strike Industries AR Castle Nut – Black

The Strike AR Castle Nut is machined from AISI 4140 steel and surface heat-treated to 45-50 HRC for robustness and durability. Its manganese phosphate finish provides an attractive matte black appearance and excellent resistance to corrosion and wear. When paired with the Strike Industries Multi-Function End Plate, there’s no need for peening or staking, simplifying installation.

Additionally, the nut features wrench cutouts for easy installation with a castle nut wrench, and its Mil-Spec dimensions ensure compatibility with AR-15 and AR-10 receiver extensions/buffer tubes. Start your new build or enhance a current rifle setup with the Strike AR Castle Nut so the receiver extension/buffer tube stays in place during operation.

COMPATIBILITY: AR-15 and AR-10 Mil-Spec dimension receiver extension/buffer tube.
