Your buffer tube and associated components suffer quite a bit at the operation of your AR-15. And quite often, today’s more modern components and accessories don’t jive with standard Mil-Spec buffer systems, even adding wear and tear to your bolt carrier group or gumming up your folding stock. Aero Precision’s buffer kits can add functionality and durability to your AR to “compensate” for your new setup’s quirks.

Sweet Threads

The Aero Precision Enhanced Buffer Tube Kit’s ramped tube design and accurate thread depth allow you to attach new carbine stocks that would otherwise take a lot of fiddling to install correctly. You might have noticed these unused threads on other tube systems—some just file them down, but Aero Precision builds their buffer tube correctly from the start.

Silky Smooth

Dealing with wear and tear is a part of shooting, but including the Aero Precision Enhanced Buffer Tube Kit into your weapon system with its extended bolt carrier supports will give your bolt a smooth ride. Custom drain holes don’t just keep your tube dry in wet places, they also allow air to escape with each round fired, further smoothing operation.

    Great product for my first build.

  • Enhancement Worth The Money

    Posted by Timothy Curry on 2nd Apr 2023

    The enhancement of this tube comes in the form of an elongated lip to catch the buffer retention detent with more than the single-thread deep of the conventional flat design. This comes at the cost of a little extra care in depressing the retainer while screwing in the receiver extension, lest spring and retainer launch themselves into oblivion. For me the extra depth of seating is worth the money - it isn't a common problem and hardly a design flaw being addressed but just a little extra piece of mind. Workmanship is, as with most parts Aero puts out, flawless.
