Q Sugar Weasel SBR .300 Blackout, 7-Inch Barrel, Brace

The Q Sugar Weasel (Q LLC part no. SW-300BLK-7IN-SHORTY) is Q LLC’s ultra-compact short-barrel rifle chambered in .300 AAC Blackout, built to squeeze maximum performance out of a genuinely short 7-inch barrel. Its 1-in-5 twist rate is tuned for stabilizing heavier .300 Blackout subsonic loads, making it a strong choice for suppressed shooting where that cartridge shines. It comes factory-equipped with a brace and a 30-round magazine, all in a 36.3-inch overall package.
