To secure lock plate on an adjustable stock for AR15, M4
I ordered 4 to replace my aluminum castle nuts! These iron castle nuts are awesome
I mean it seems well built , but the sticker package wouldve been worth the price of the castle nut! Would buy again and plan to do business in the future!
The castle nut does exactly what it's supposed to do. no issues whatsoever, it's BCM what do you expect??
Top notch quality and service, they even sent me a few free BCM decals with my order. A company like this is hard to find nowadays.
Works like it should, timely shipping to Alaska
It wasn't the prettiest castle nut. It wasn't the fastest castle nut. It didn't have the best luck with the lady nuts, but through sheer determination and persistence, this castle nut matured and became the most adequate means of attaching a receiver extension to a lower receiver. No complaints.
BCM makes great quality products, I experienced this when replacing the SBA3 brace on my BCM lower. First, their stake job was by far the best I have come across; the only way I could remove that castle nut was by cutting it off. Purchased another castle nut from BCM, great quality and fast shipping. I also purchased the BCM qd endplate and was easy to stake. Love BCM products.
Great fit, worked well
i ordered 2 one for my 300blk out build and other to lock down the pistol brace on my kriss vector. the item had a great finish no burns in the threads. what more could you want in a castle nut
