Lightweight Aluminum Castle Nut

Only a third of the weight of a mil-spec steel castle nut, the Fortis Standard Castle nut offers a simple way to trim fat from your AR-15 build.  This 7076-T6 aluminum ring features standard cuts for an AR-15 multitool, and is installed the same way a regular nut is.  The smaller cuts provide the perfect recess to stake your endplate into the castle nut, preventing rotation.

This part makes saving ounces on a lightweight build simple, without sacrificing the durability overall.  The higher grade of aluminum means it will work as an excellent retainer to keep your receiver endplate and buffer tube secure.

  • Material: 7075-T6 Aluminum

Nice Touch

I chose this castle nut due to the appearance and light weight. I assembled this castle nut in conjunction with a Radian end cap featuring a titanium swivel QD. The finished assembly looked phenomenal and I am well pleased. I used a designed wrench and torqued to 40 foot pounds. This castle nut performs as advertised and I highly recommend. I did use 3M painters tape on the nut to eliminate any scratches. If you are looking for an added touch on your build, this nut rocks!

Thank you for your review and for choosing our Fortis Standard AR-15 Castle Nut. We are glad to hear that it added a nice touch to your build and that you were pleased with its appearance and lightweight design. We also appreciate your recommendation and are happy to know that it performed as advertised. Thank you for the helpful tip on using 3M painters tape to prevent scratches. We value your feedback and hope to continue providing quality products for your builds.

Best nut I ever got

This thing is sweet. Very light but strong. I torqued it to 40 ft pounds with no worries. I got a few compliments to. Stop looking around and get one from AT3 now. You'll be glad you did!

Thanks for sharing your feedback! We're glad you're satisfied with your purchase.
