Yankee Hill Machine Company Victra-20 Choke Cone Features The Yankee Hill Machine Victra-20 Choke Cone is machined specifically for the Victra-20 a modular 20 gauge shotgun suppressor and is not a general-purpose shotgun choke. Positioning the choke constriction at the end of the suppressor rather than inside the barrel as on a standard shotgun puts the pattern-forming geometry in the optimal location for a suppressed host gun. This Improved Cylinder cone is one of three choke sizes offered for the Victra-20 system letting shooters tune their shot pattern to the range and application they are shooting. Because the choke s job is to shape pellet spread swapping cones is the simplest way to adjust performance without changing the suppressor itself. Constructed from 17-4 stainless steel the choke cone is built to handle the heat and pressure cycling that comes with repeated suppressed shotgun use without degrading over time. Yankee Hill Machine manufactures the Victra-20 choke cones entirely in the USA keeping production and quality control in house. The cone ships with no additional finish leaving the stainless steel surface in its natural state for straightforward maintenance and inspection. For Victra-20 suppressor owners who want to dial in their shot pattern for a specific gauge and application the Victra-20 Choke Cone is available for sale at GrabAGun.
