Yankee Hill Machine Company Victra-20 Jam Nut Features The Yankee Hill Machine Victra-20 Jam Nut is designed to lock the VICTRA-20 modular shotgun suppressor mount securely onto its host firearm keeping the mount from loosening under recoil and repeated use. Machined from 17-4 stainless steel it offers strength and corrosion resistance that holds up to the demands of suppressor mounting hardware. The Melonite finish adds an additional layer of wear resistance helping the part maintain its function and appearance over time. At a compact 0.25 inch depth and 1.1875 inch diameter it is a small but essential piece of the overall mounting system. This jam nut is included with the purchase of a VICTRA mount but having a spare on hand is useful for anyone servicing or reconfiguring their suppressor mount setup. Yankee Hill Machine manufactures the part in the USA reflecting the same build quality found across their suppressor mount lineup. Keeping the mounting hardware properly torqued and secured is critical to safe and reliable suppressor use on a shotgun platform. This Yankee Hill Machine Victra-20 Jam Nut is available for sale at GrabAGun for VICTRA mount owners who need a replacement or spare.
