The Strike Industries Enhanced Castle Nut and Extended End Plate (brand part number ARECN&EEPRED) upgrades a factory AR-15 buffer tube assembly with a matched, lengthened castle nut and extended end plate finished in red. Strike Industries lengthened the steel castle nut to match the extended end plate, so it supports more of the receiver extension’s threaded area than a generic parts-kit nut while also cleaning up the look of the rear of the lower. The extended end plate carries a Quick Detach sling swivel mount pushed back away from the webbing of the shooting hand, a real difference for anyone who’s felt the startling pinch of a sling mounted on a standard, flat QD end plate during hard manipulations. Built as a combo unit, it drops in as a direct upgrade over the stock castle nut and end plate.
