YANKEE HILL MACHINE VICTRA-12 MODULAR 12 GAUGE SHOTGUN SUPPRESSOR The YHM Victra(TM)-12 shotgun suppressor is the result of YHM's leading design, engineering and technology capabilities in the field of firearm suppression. The Victra-12 features a modular design, meaning the user can remove sections to best meet their needs for sound suppression, firearm balance, weight and length. In the full 12" configuration, the Victra-12 reduces most commercial shotgun loads to 135 dB at the shooter's ear. Most users will also note a decrease in felt recoil, which allows the shooter to concentrate on the target. The VICTRA-12 attaches Mfg: Yankee Hill Machine Co., Inc.
