Strike Industries AR15 Enhanced Castle Nut & Extended End Plate

Available in Grey

Yet another first, the Strike AR-15 Enhanced Castle Nut and Extended End plate combo represent Strike Industries’ dedication to thinking outside the box. The SI Enhanced ECN and EEP stand out from the generic parts kit units in both aesthetics and function. The steel castle nut has been lengthened to match the extended end plate, supporting more of the receiver extension’s threaded area, and improving aesthetics. The extended end plate features a Quick Detach sling swivel mount, pushed back away from the webbing of the primary hand. This allows weapons manipulations in tight spaces and under stress, without the startling pain that can result from a pinched hand when using a sling attached to a standard, flat QD end plate.


Package includes:
- 1x Enhanced Castle Nut
- 1x Enhanced End Plate
- 1x Set Screw


- Aesthetic upgrade
- Centrally placed QD for right or left hand sling use
- Easy drop in installation
- Simplified installation of takedown pin detent via set screw.

Note: First position will be lost


Note: Receiver Extension Tube (RET) may become damaged if ECP is installed on RET and then forced far enough rearward to allow full threading onto Billet or polymer lower receivers that have a RET support flange with a depth greater than 0.503."
