The MAGNUS is the quietest .30 cal suppressor on the market for everything - .223's, 6mm's, 6.5mm's, 7mm's, and .30's - up to .300 Norma Magnum. The Magnus-SR shares the same SR (Secondary Retention) mount as the 338 Ultra SR and Dominus SR suppressors. The Magnus-SR is 0.70-inch longer and 2.9 ounces heavier than the Magnus-CB. This version has the same Hard-Use/Full-Auto as the Dominus-SR, ie, Lifetime to exceed at least 10 SURGE cycles on a 10.5" M4 / MK18. The Magnus-CB and Magnus-HUB are NOT full-auto rated due to the mount being insufficient.
