How many times have you heard this: “Well, that’s the way we’ve always done it.”? It doesn’t matter where it is, that’s dangerous talk. When you’re talking about a subject as dynamic and progressive as tactical firearms, it’s downright restrictive, antique thinking. Something as seemingly simple as the traditional installation and peening of the AR 15 castle nut bogs down progress. In order to free the armorer who wants to rebuild rifles, or swap out parts as better choices come to market, Strike Industries has developed the SI Anti-Rotation Castle Nut (ACN) and Multi-Function End Plate (MFEP.)

A Simple Idea Opens Doors for You

Strike Industries was built on supplying the small arms community with superior versions of products that other manufacturers don’t bother with. Their Anti-Rotation AR 15 Castle Nut and Multi-Function AR End Plate Set features a detent set screw and anti-rotation set screw to secure your system rather than using the old way of securing the receiver extension by peening or staking. The result is added flexibility you might never have thought about before but will enjoy when it comes time to replace worn parts or try something new. You’ll no longer hesitate to do something just because it’s a pain in the neck to disassemble.

Be Flexible, Stay Ahead

You want every edge you can get. Now, you can easily stay an extra step ahead with the freedom and flexibility brought to you by the Strike Industries Anti-Rotation Castle Nut and Multi-Function End Plate.
The Multi-Function AR End Plate (MFEP) allows you to choose your preferred sling type. Whether you use a hook and loop, traditional sling loop or you need a quick detach socket, they’re all here. You’re not married to one or another and you can change as often as you like without changing the end plate. Add this to the easy removal of the Anti-Rotation Castle Nut and your AR system is now an ultra-flexible weapon system that you can retool for whatever the future holds. Stay ahead of the competition, and Strike First.

    This product is awesome. So glad I don't have to stake my castle nut anymore. It is a much smarter design than standard mil-spec castle nut. The ratchet locks up tight and it is easy to remove if you want to switch out your receiver extension (a.k.a. buffer tube). Having multi-function sling mount is a plus. Can't go wrong with Strike Industries' products.

    Principally bought this endplate for it's QD feature, but liked the versatility of other sling mount options. Having bought other SI products, I had no reservations, but this one sucks. Starting with having to Dremel down the tab that sits on the inside of the buffer tube ring to get it to fit around any of my buffer tubes. Once I got that done, I had to look through several of my local hardware stores for a hex wrench small enough to fit the takedown pin detent spring screw, because SI does not provide one. Finally got the thing installed and tried out the QD mount. I have a few slings from $35-$80, and all of them got stuck inside the QD mount, requiring two handed removal and much effort. And now that I've dremeled the endplate, I can't return it. I think I'll stick with the Tactical Link Z-360.
