Battle Arms Development 6-Position Mil-Spec Buffer Tube Assembly

The Battle Arms Development 6-Position Mil-Spec Buffer Tube Assembly is a precision AR-15 receiver extension built for shooters who demand reliability and durability in their rifle platform. Whether you're running a carbine build, an SBR, or a competition rifle, this buffer tube gives you six adjustment positions to dial in the stock fit and cheek weld that works for your setup. Made in the USA from 7075-T6 aircraft-grade aluminum and finished with Type III hard anodizing, it's engineered to withstand the rigors of the range, the field, and everything in between.

Battle Arms Development has been refining small arms components since 2009, focusing on design and precision manufacturing. This buffer tube reflects that commitment—it's impact-forged and CNC-machined to tight tolerances, so it mates reliably with standard AR-15/M16/M4 lower receivers and accepts mil-spec stocks without guesswork. The hard black anodized finish resists corrosion and wear, keeping your build looking and functioning clean for years.

If you're customizing an AR platform or refreshing an existing rifle, this is the kind of foundational component that rewards attention to detail. Six positions mean you can adjust for body armor, different shooting positions, or just personal preference—without hunting for proprietary adapters or worrying about compatibility headaches.

Frequently Asked Questions

What AR-15 lower receivers does this buffer tube fit?

This is a mil-spec buffer tube designed to fit standard AR-15, M16, and M4 lower receivers. If your lower is mil-spec spec'd, this assembly will mate up without issues.

Can I use different stocks with this tube?

Yes. Since it's mil-spec, it accepts any mil-spec collapsible stock or fixed stock designed for standard AR buffer tubes.

What makes the 7075-T6 aluminum a good choice for a buffer tube?

7075-T6 is an aerospace-grade alloy known for high strength-to-weight ratio. Combined with impact forging and hard anodizing, it delivers the durability needed for a critical wear part while keeping weight down on your build.

Does this come with a stock installed?

No. This is the buffer tube assembly only; you'll need to source a mil-spec stock separately to complete your setup.
