The Strike Industries Enhanced Castle Nut and Extended End Plate with QD (brand part number SI-AR-ECNEEP-BK) upgrades both the look and function of a standard AR-15 parts kit castle nut and end plate. Strike lengthens the steel castle nut to match the extended end plate, so it supports more of the receiver extension’s threaded area for a cleaner, more finished look. The extended end plate carries a Quick Detach sling swivel mount pushed back away from the webbing of your primary hand, letting you manipulate the weapon in tight spaces and under stress without the pinch that a standard, flat QD end plate can cause.
