The Strike Industries AR Castle Nut and Extended End Plate Steel kit delivers enhanced functionality for AR-15 platform builds and upgrades. This precision-machined steel combination provides improved sling attachment options and streamlined buffer tube installation compared to standard mil-spec components.
What Makes This Different
The extended end plate design incorporates integrated sling attachment points that eliminate the need for separate QD mounts or traditional sling swivels. Strike Industries engineers this kit from heat-treated steel rather than aluminum, providing superior thread engagement and resistance to deformation under torque. The castle nut features enhanced wrench flats for secure installation without specialized tools.Key Features
