The Primary Weapon Systems Enhanced Buffer Tube with ratcheting castle nut and end plate is a simple reliability upgrade for your AR-15 pistol or carbine. The PWS tube goes on the gun a bit differently from a standard buffer tube (aka receiver extension), and Brownells Gun Tech Steve Ostrem shows us how it’s done. Unlike the mil-spec component, the PWS Enhanced Buffer Tube requires no staking or Loctite® because its ratcheting system locks the tube securely in place. Once installed, it provides extra support for the carrier, which results in improved overall reliability of your AR-15.

I use the PWS QD setups in everything I build now. Easy to install and easy to remove for barely more money than just the Magpul or BCM QD end plate.
Is it American made? Because I have a strike industries while it works just fine I was disappointed that it was made in Taiwan
Ummmm, why? If you dont own a spring loaded center punch… you should not even think about doing this. Silly crap to take your money.
What a great upgrade! I’ll keep this in mind for future builds!
😎👍🏼
no way! thats awsome that you dont have to stake it!
I have the PWS ratcheting castle nut on 2 rifles, they are fantastic and worth the money.
