The new 338 ULTRA is the quietest .338 caliber suppressor on the market today for everything up to .338 Lapua Magnum, including your 6's, 6.5's, 7's, and .30's. It offers class leading suppression levels with extreme light weight.
 
The 338 ULTRA SR has the same SR (Secondary Retention) mount as Thunder Beast Dominus-SR, Dominus-K-SR, and Magnus-SR. This model is 0.60-inch longer and 2.8 ounces heavier than the BA version. 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 BA version of the 338 ULTRA is NOT full-auto rated due to the mount being insufficient. The GEN2 SR weight is 0.2 ounces lighter than the GEN1 version.
 
The RR variants of the 338 ULTRA almost double the recoil reduction (compared to a bare muzzle) of the normal flat-cap version of the suppresor. On 338LM, the 338 ULTRA-RR has a recoil reduction of 54% --- vs normal version 32%.
