Je Machine Tech Receiver End Plate Features The Je Machine Tech Receiver End Plate sits between the lower receiver and the castle nut giving the buffer tube assembly a solid properly aligned mounting surface on an AR15/M4 pattern lower. Steel construction gives the end plate the strength to handle the constant pressure from the castle nut and buffer tube without deforming over time something a lower quality stamped part can struggle with. The black finish matches standard AR furniture and resists the wear that comes from repeated handling and holster or sling contact. This part also helps retain the takedown pin detent and spring so it plays a small but important role in keeping the rear takedown pin functioning correctly. At just 0.30 pounds the end plate adds negligible weight to a build while providing a long lasting functional connection point for the stock assembly. It is built to the standard AR15/M4 specification so it fits directly onto compatible lower receivers without any fitting or machining required. This makes it a straightforward replacement for a damaged or missing original end plate or a simple upgrade when building a lower from a stripped receiver. Builders and armorers completing an AR15/M4 lower build will find this Je Machine Tech Receiver End Plate available for sale at GrabAGun.
