Dbst A2 Shorty Buffer Tube

The Doublestar Corp Dbst A2 Shorty Buffer Tube is a specialized AR-15 receiver extension designed for builders aiming to create shorter, more maneuverable rifle profiles. This buffer tube is ideal for compact configurations, particularly in applications where reduced length is essential, such as short-barreled rifles (SBRs) or AR pistols.

At 7 inches in length and weighing just 0.19 lbs, this buffer tube effectively reduces the overall footprint of your AR-15 build compared to standard carbine or rifle-length extensions. The A2-profile design maintains dimensional consistency with mil-spec lower receivers, ensuring reliable cycling with standard spring and buffer systems. Note that this tube does not include a carbine buffer or spring, which must be sourced separately to complete your build.

Tactical professionals and serious hobbyists will find this shorty buffer tube advantageous for building compact AR platforms. Pairing this tube with the ACE Entry stock creates an entry-length system commonly used in law enforcement, military, and civilian defensive configurations. Doublestar's established reputation in the AR component market makes this buffer tube a reliable choice for enhancing your firearm's performance.
