SIG Sauer is following up on the success of its popular SB15 Pistol Stabilizing Brace with the introduction of a new streamlined version of the original brace. The company is calling it the SBX Pistol Stabilizing Brace.
The main difference between the new SBX and the original SB15 is that the SBX features a slimmer design and a thicker strap for increased stability. The SBX has a length of 6 1/4 inches, a height of 6 1/4 inches and a width of 2 1/8 inches; the SB15 is slightly larger with a length of 6 3/4 inches, a height of 7 inches and a width of 2.175 inches. The SBX is also slightly lighter than the SB15, weighing in at 10 ounces instead of 12.1 ounces.
As with SIG's SB15, the SBX fits all pistols equipped with an AR-style buffer tube 1 to 1.2 inches in diameter and complies with ATF requirements, meaning there is no change to the firearm's classification when the SBX is attached. The SBX is manufactured in the U.S. using durable elasto-polymer.
Only slightly more expensive than the SB15, the new SIG Sauer SBX Pistol Stabilizing Brace is available for $149.
