Strike Industries Enhanced Castle Nut (ECN) and Extended End Plate (EEP) Kit

 

Details:

Strike Industries has made a name for itself addressing needs that are frequently overlooked by the rest of the firearms industry. With a reputation for attention to detail, you can bet that when Strike offers a parts kit, it’s something special. Strike Industries’ Enhanced Castle Nut and Extended End Plate kit is no exception. When you install these pieces on your rifle you’ll wonder why someone didn’t do it this way sooner.

When you order a Strike Industries Enhanced Castle Nut (ECN) and Extended End Plate (EEP) kit you’ll receive an Extended QD End Plate and an Enhanced Castle Nut and a set screw for simple installation of the takedown pin detent.

The Strike Industries EEP includes a Quick Detach Sling Swivel Mount in the center where it functions ambidextrously. The mount has been repositioned from the traditional placement, eliminating the risk of painful pinches to the webbing of the operator’s primary hand. You’ll handle your weapon more confidently, even in close quarters, because you don’t have to worry about painful accidents due to poor ergonomics.

Strike designed the ECN to better support the threaded part of your receiver’s extension and match the length of the Extended End Plate. The result is a better looking, more secure and functional ECN/EEP kit that you’ll be happy to have on your rifle whether you’re out on maneuvers or at the range.

Strike’s team of engineers and craftsmen has done it again with the Enhanced Castle Nut and Extended QD End Plate. They’ve made simple changes to small parts that others overlooked and improved the operator’s experience in the real world.

Note: Receiver Extension Tube (RET) may become damaged if EEP 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."

    This is the second ECN/EEP I've gotten. One red and one blue for different rifles. Easy install if you have the right tools and take your time. Torque wrench is a must. I've seen some reviews about varying colors. If you mix and match from different manufacturers you can almost guarantee a color variance due to the anodizing differences between makers although their red matches many others their blue is lighter than most. SI colors have been a spot on match for every part I've gotten from them in both red and blue (trigger guards, charging handles, pivot/takedown pins, ECN/EEP, selector switches, angled QD mounts).

  • Excellent Product, Poor coloration

    I purchased this endplate/castle nut combo for a custom match rifle build, and the aesthetics are awesome for it. Just different enough to stand out, but not obnoxious or overdone. Super easy install and lightweight are a plus. My only issue is with the color; While the picture online shows a bright, deep blue color that I was expecting to match nicely with the other bright blue anodized parts on my rifle, the actual part has an almost "frosty" matte finish, causing it to look almost purple in color. If I had to order it over again I would have gone with the black one instead, as the difference in texture and color saturation is pretty extreme compared to my other parts and the product picture.

  • Great product..

    Wish I would have bought this with the rest of parts first. Aero precision castle nut that came with my buffer kit tube actually cracked after firing first so I got this to replace it and couldn’t be happier. Looks great and protects tube threads.
