Let’s Talk About DoubleStar Shorty A-2/ Entry Length Rifle Buffer Tube

The DoubleStar Shorty A-2/ Entry Length Rifle Buffer Tube is designed for those seeking a compact AR-15 platform without sacrificing the recoil-taming benefits of a rifle buffer system. DoubleStar, a reputable name in the AR parts industry, offers this tube as a solution for builds requiring shorter overall length, particularly when paired with specific entry-length stocks. For shooters prioritizing maneuverability in tight spaces or those building a specialized CQB (Close Quarters Battle) rifle, this buffer tube presents an interesting option.

My journey to this particular buffer tube started with a desire to build a compact AR-15 pistol-caliber carbine (PCC). I needed a buffer system that wouldn’t add unnecessary length while still providing reliable cycling with 9mm ammunition, and the promise of rifle-length buffer characteristics in a shorter package was enticing. Upon receiving the DoubleStar Shorty A-2/ Entry Length Rifle Buffer Tube, I immediately noted its robust construction and clean, hard coat anodized finish. The weight felt substantial, indicating quality materials and precise machining.

Compared to a standard carbine buffer tube, the difference in length was immediately apparent, promising a significant reduction in the overall length of my intended build. I’d considered a few other options, including pistol buffer tubes and even some specialized short-stroke systems, but I chose the DoubleStar primarily for its compatibility with readily available entry-length stocks and its promise of a smoother recoil impulse compared to shorter buffer systems. My initial impression was one of cautious optimism; the build quality seemed excellent, but the real test would be its performance on the range.

Real-World Testing: Putting DoubleStar Shorty A-2/ Entry Length Rifle Buffer Tube to the Test

First Use Experience

My initial testing took place at an outdoor shooting range, utilizing my AR-9 PCC build with a 9mm upper receiver and a compatible entry-length stock. I tested the DoubleStar Shorty A-2/ Entry Length Rifle Buffer Tube with a variety of 9mm ammunition, ranging from standard 115-grain FMJ to heavier 147-grain subsonic loads. Performance remained consistent even in slightly dusty conditions, with no noticeable malfunctions related to the buffer system.

The DoubleStar Shorty A-2/ Entry Length Rifle Buffer Tube provided a noticeable reduction in felt recoil compared to a standard carbine buffer system in a similar 9mm build. I didn’t experience any issues with cycling or reliability right out of the gate, which was a pleasant surprise. The reduced length made the rifle noticeably more maneuverable, confirming my initial intention for this build.

Extended Use & Reliability

After several months of use, and hundreds of rounds downrange, the DoubleStar Shorty A-2/ Entry Length Rifle Buffer Tube has proven to be exceptionally reliable. There are no signs of wear and tear beyond minor cosmetic scratches from normal use. The hard coat anodized finish has held up well, showing no signs of chipping or fading.

Maintenance has been minimal; a quick wipe down with a lightly oiled cloth after each range session is all that’s required. Compared to my previous experiences with standard carbine buffer systems, the DoubleStar Shorty A-2/ Entry Length Rifle Buffer Tube has provided a smoother, more consistent recoil impulse and has proven to be just as durable. It has exceeded my expectations for a compact buffer system.
