How To Install the PWS Enhanced Buffer Tube: Product Spotlight ~ VIDEO

Iowa – -(Ammoland.com)- Brownell’s Gun Tech Steve Ostrem shows how to install the Primary Weapons System Enhanced Buffer Tube on a receiver.

The Primary Weapon Systems Enhanced Buffer Tube with ratcheting castle nut and endplate 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 the improved overall reliability of your AR-15 rifle

OK, so installation is straightforward. Now how do you take it off if you want to switch to a different style receiver extension?

“The ratcheting system stays in place until you put a wrench on it and take it off”.

I have never staked it or used locktight. I just put one hell of a torque on it with the wrench. I have never had one get loose. He should have sold us on putting an endplate on it that you can use for your sling while he was at it. I never leave home without it.
