Layton's Review of Primary Weapons Systems EBT Mod 2 End Plate and Castle Nut

These are a great addition to a build. Staking a castle nut can be difficult if you don’t have a vise and vise block for a lower. These make securing the buffer tube extremely easy. I’d recommend adding some blue loctite as well. I’ve had one loosen up on me with a lot of use.
