The SF® Ryder 22-S is a lightweight, thread-on suppressor optimized for .17 HMR, .22LR and .22 Mag rimfire pistols and rifles. Built to exacting standards like SureFire’s SOCOM Fast-Attach® suppressors, it features a patented aluminum body with rounded ends and flutes for reduced weight without sacrificing strength. Weighing just over 5 ounces and measuring only 5.4 inches long, the SF Ryder 22-S minimizes effects on weapon weight and maneuverability. SureFire’s proprietary heat-treated stainless steel baffles provide superior sound attenuation and tremendous durability even during full-auto use. SureFire’s proprietary internal design reduces carbon buildup and keeps the suppressor clean longer. It’s also easy to disassemble, clean, and reassemble. The SF Ryder 22-S is simply the best thread-on suppressor available for .17 HMR and .22 shooters.
