Quick Detach Steel End Plate and Castle Nut Kit
This end plate kit pairs a steel quick detach end plate with a castle nut, giving builders a sling attachment point at the rear of the receiver extension. The quick detach design lets you mount and remove a compatible QD swivel quickly, which suits tactical setups, range work, and competitive shooting where sling configurations change often. The castle nut secures the assembly during stock or buffer tube installation. This kit is made in the USA.
As with any AR build, confirm the components match your platform and receiver extension before installation. Verify your QD swivel is compatible with the quick detach socket, and use a castle nut wrench with proper staking practices during assembly.
Need a different configuration? Compare the mil-spec end plate kit or the ambidextrous dual loop end plate kit, and stock spares with our steel castle nut five pack.
