Details:

Most of us are guilty of a false belief that for something to be important it needs to be big and flashy. We all fall under the spell of a hot new manufacturer or succumb to the wiles of the do-hickey of the month now and then. The fact is that evolution isn’t just something that happens in big leaps. Sometimes it’s a small change that gives you a new leg up on the game. Primary Weapons Systems understands that. When they say they believe in strength through evolution, they’re talking about the whole package, not just the big expensive components. Case in point: The PWS Ratchet Lock Castle Nut and End Plate Set. Yes, it’s just a castle nut and end plate. It’s a pretty simple combination, yet the Ratchet Lock Castle Nut raises the bar in buffer tube attachment.

Primary Weapons Ratcheting Castle Nut: No More Staking

The Primary Weapons Systems Ratchet Lock Castle Nut and End Plate Set allows the armorer to attach either commercial type or Mil-Spec Buffer Tubes to your weapon system without the pain-in-the-neck of staking. Yes, it’s secure, and guess what PWS created this option considering the possibility that you might want or need to change a buffer tube before your weapon deadline. You’re not married to the installation and it won’t require you to destroy anything to get it apart. You might even do it without any colorful language.

The end plate includes and integrated QD mounting point for your sling swivel so you can get hooked up and get on with it. Is it a huge thing? That depends on how bad you need it today. Is it an evolution? Definitely. Why do we need it? Because It's Time we stop suffering over the small stuff and evolve.

    I bought one of these a few years ago for some up and coming builds. For one reason or another I never git used and just sat in my spare parts box until last night. I started a modern tacticool AR build and decided to use it instead of the regular BCM QD mount, plate and castle nut. It went on extremely easy and both works as advertised as well as looks great too. I would recommend one to anyone that wants it right and tight now without any special knowledge of staking or the extra work. I'm very pleased with the purchase and would use one again on this type of build.

    Easy to use and stays tight but can easily be taken off.

  • Just what I needed

    I was tired of having to re-tighten my milspec endplate/castle nut due to being staked poorly out of the factory. The PWS rachet lock castle nut and endplate kit is exactly what I needed. Now I can just focus on drills vs. worrying about my castle nut backing out during non-static range drills session. Now my Springfield Saint Victor 5.56 rifle is perfect...
