Yankee Hill Machine Co Victra-20 Features The Yankee Hill Machine Co Victra-20 suppressor is constructed from 7075 aluminum and 17-4PH stainless steel finished in hard anodize and Melonite respectively for a dual-material construction that balances lightweight durability with the heat and corrosion resistance required for sustained shotgun use. Rated at 132 dB and compatible with 20-gauge shells up to 3.5 the Victra-20 delivers meaningful sound reduction across the full range of 20-gauge loads without restricting ammunition selection. The modular 4.4 configuration option allows the shooter to tailor length and weight to their specific platform and application without tools. The YHM choke thread mount utilizes the host firearm s existing choke threads for a clean manufacturer-specific installation that requires no permanent barrel modification. At 1.95 wide and 2.7 tall the Victra-20 maintains a profile sized for the 20-gauge platform while providing the internal volume required for effective sound suppression. Additional compatibility with .300 Blackout subsonic loads on barrels 7.5 or longer extends the Victra-20 s utility beyond dedicated shotgun use. Yankee Hill Machine Co manufactures the Victra-20 in the U.S.A. to the same standards applied across their suppressor lineup delivering a purpose-built 20-gauge solution for hunters and sporting shooters who demand reliable suppressor performance from a modular easy-mounting platform.
