Donny Silencers FL KOI 1.22 x 7 inches Bolt End Cap – The Ultimate Silencing Solution for 5.5mm Airguns
Experience a new level of quiet precision with the Donny Silencers FL KOI Bolt End Cap, designed specifically for 5.5mm FX air rifles (M20x1 threading). Engineered by Donny Du, a passionate shooting expert and co-owner of Saber Tactical, this silencer delivers superior sound suppression without compromising on performance or style. Whether you’re a casual airgunner or a seasoned competition shooter, the KOI promises to enhance every shot with its flawless craftsmanship and innovative design.
The KOI stands out with its rugged new front cap and signature DonnyFL grooved body, which not only look sleek but also offer an exceptional grip for quick, confident handling in the field. Despite boasting the smallest outer diameter among DonnyFL’s premium lineup, this compact marvel packs a punch with strategically placed vent holes around the front cap to maximize noise reduction and airflow. This means you get the best of both worlds: minimal bulk and high-performance suppression.
Built with durability in mind, the KOI features a precision CNC-machined mono-core design. Its sandblasted and anodized finish ensures it resists wear and tear, maintaining a sleek, matte look no matter how intense your shooting sessions get. The modular rear end cap system is another standout feature, allowing you to swap easily between 1/2 x 20 Bolt, FX (M20x1) Bolt, or 1/2 x 20 Cone options, making it compatible with a broad range of air rifles. Plus, it comes pre-wrapped in felt for added protection and a polished fit.
