The MAGNUS is the quietest .30 cal suppressor on the market for almost every caliber — .223’s, 6mm’s, 6.5mm’s, 7mm’s, and .30’s — up to .300 Norma Magnum. The only thing quieter — in some cases — is a 338 ULTRA GEN2, which is larger.
The MAGNUS-SR shares the same SR (Secondary Retention) mount as our Dominus-SR, Dominus-K-SR, and 338 ULTRA SR. This model is 0.70-inch longer and 2.9 ounces heavier than the CB version. This version has the same Hard-Use/Full-Auto rating as the DOMINUS-SR, i.e., Lifetime to exceed at least 10 SURGE cycles on a 10.5″ M4 / MK18. The other versions of the MAGNUS are NOT full-auto rated due to the mount being insufficient.
Best-for: Hunting, PRS.
The Magnus-K is the best choice if you want the least length added to your rifle. Suppression is between an Ultra 5 and an Ultra 7 (Gen2).
