Pws ratchet castle nut & end plate - Primary Weapons Systems EBT Mod 2 End Plate and Castle Nut

I have used the PWS ratchet castle nut and endplate on 10 by builds. I use to stake all my castle nuts but this system is better for my needs. I've never had any back out on me and they are super easy to install. Also easy to remove when needed. Some people say they back out and that it isn't good to reuse them as the detent will wear down but I've never had anything like that happen over the past two years of using them. If you don't want to be bothered with staking the castle nut or or this is your first build then I highly recommend this product.
