While DefenseReview was chatting with John “Chappy” Chapman at the Laser Devices, Inc. booth at SHOT Show 2010, he told us we absolutely had to go take a look at the PWS Enhanced Buffer Tube, MilSpec, which is designed to replace the standard buffer tube on tactical AR (AR-15) carbines and SBRs (Short Barreled Rifles)/subcarbines. So, we headed down to the Primary Weapons Systems (PWS) booth and did just that. PWS bills their enhanced buffer tube as “the first major upgrade and improvement to the buffer tube in years”.

The PWS Enhanced Buffer Tube, MilSpec is a one-piece aluminum billet buffer tube that’s machined out of 7075 aluminum for strength and reliability, while remaining lightweight.

According to the company website, PWS Enhanced Buffer Tube, MilSpec features include:

– One piece construction eliminating the castle nut and ensuring that when installed, the buffer tube cannot become loose.

– Attachment system automatically indexes the buffer tube perfectly straight.

– The bottom of the interior buffer tube extends a lip into the receiver, supporting the bottom rear of the bolt carrier, counteracting the carrier tilt present in some piston systems.

– Two QD sling swivel attachments are machined into the front of the buffer tube allowing ambidextrous connection of your QD slings.

– The buffer tube is fluted to allow debris to be pushed out of the way, and a drain hole has been placed in the bottom of the tube, allowing for draining of water when the rifle is parallel to the ground.

– A dead blow buffer is securely installed in the rear of the buffer tube to reduce carrier speed by an average of 10%, and dramatically reduce felt recoil.

The website also makes this statement: “The PWS Enhanced Buffer Tube is Mil-Spec.”

DefenseReview snapped a couple of pics of the new PWS buffer tube, and we have to say that it looks interesting. However, we haven’t T&E’d it, yet.

Stay tuned for our upcoming article on the PWS DC-12 (Defensive Carbine, 12.5 inch) 12.5″ long-stroke gas piston/op-rod SBR (Short Barreled Rifle)/subcarbine complete upper receiver assembly.
