The new Ultra Compact Pistol Sabertube and VERT Buffer System is designed to keep an AR-15 pistol extremely compact. The 6061 aluminum Sabertube adds only 4.75″ from the rear of the receiver and is machined with a dimpled pattern to reduce weight (3.9 ounces total). This tube makes use of the same VERT Buffer System found in Battle Arms Development’s VERT line of PDW stocks.
It’s short, light, and available now from Battle Arms Development.
