Great for a first-time builder! - Primary Weapons Systems EBT Mod 2 End Plate and Castle Nut

I'm really happy that I saw this ratcheting castle nut system mentioned in a TFB article and was able to find it here on OpticsPlanet! I included this ratcheting castle nut on my first two builds, where there was a very high probability that I would go full-on "adult lego" and end up swapping in/out a lot of parts. By the time I got my lower Cerakoated and assembled with the rifle-length adjustable buffer tube I eventually swapped in, I had assembled and disassembled the whole lower four times. Not only was this easy to assemble and disassemble with just an armorer's wrench, this holds securely without staking, and was also able to be Cerakoted to match my lower without interfering with the ratchet system. This thing is awesome, I love it!
