The Aero Precision Enhanced AR-15 buffer tube is designed to deliver increased reliability and security to your AR-15 build. The buffer tube is compatible with all standard carbine-stock options that use Mil-Spec buffer tube dimensions.

Enhanced Performance

The Aero Precision enhanced buffer tube has carrier support extensions that fully support and guide the bolt-carrier group into the buffer tube to prevent carrier tilt and reduce wear on critical components. The support extensions have been designed to extend out to either side of the buffer retaining pin to both secure the pin and prevent recoil from working the buffer tube loose. The position guide drain holes allow water to drain when operating in wet conditions. The ramped tube allows the easy installation of traditional carbine stocks, and the attachment threads have been precisely cut to the proper depth to give the tube a cleaner look as well as preventing collapsible stocks from getting hung up on unneeded threads.

Quality Construction

The Aero Precision buffer tube is built to military specifications and accepts all Mil-Spec dimension stocks. The tube is made from 7075 T6 aluminum, weighs in at just 3.88 ounces, and carries a hard coat anodized finish for superior protection against the elements and wear.

Easy Installation

The Aero Precision enhanced buffer tube installs without special tools or gunsmithing knowledge. The stock easily attaches to the enhanced buffer tube by just holding down the adjustment piece and pushing the stock onto the tube.

  • Excellent Buffer Tube

    Posted by RGCGFMT on 2nd Oct 2022

    This will be my new go-to carbine buffer tube. Excellent fit and finish. I appreciate the support of the rear of the bolt carrier and the increased insurance against rotation of the tube while torquing, via the buffer retaining pin. The angled surface on the rear of the tube where the stock LOP adjustment pin contacts during installation is also nice, as it eases installation of the stock. There is also enough relief cut behind the threads to allow the castle nut and end plate to rotate freely around the tube during installation into the lower receiver, which eases installation of the takedown pin detent spring. Finally, the enhanced buffer tube is very reasonably priced for the thought and features that went into the design. Great part. Don't hesitate.

  • Can’t wait to use it

    Bought this buffer tube from this site since it was cheaper than Brownells. Exactly as to be expected of a Aero product. Heads up, however, you need to buy the castle nut and end plate separate as this is only the buffer tube.
