DonnyFL KOI Suppressor 1/2 UNF 4.5-5.5 – Compact airgun sound moderator

The DonnyFL KOI is an airgun suppressor designed to reduce muzzle report during shooting. This unit features a 31mm diameter body with 18cm length and mounts via 1/2 UNF thread. Compatible with 4.5mm (.177) and 5.5mm (.22) calibre air rifles.

Construction and materials

Built from aluminium, the suppressor weighs 138 grams. The front ventilation ports and robust construction provide effective sound moderation. The black finish offers a professional appearance. An engraving option is available for identification purposes.

Application and use

Designed for target shooting and range use with air rifles. When mounting this suppressor, you must re-zero any optics as point of impact will shift compared to unsuppressed shooting. Select a suppressor rated for at least one calibre larger than your projectile size to prevent baffle strikes.

Integration and compatibility

The suppressor attaches via 1/2 UNF barrel threading. Suitable for air rifles in both 4.5mm and 5.5mm calibres. Verify your barrel thread compatibility before ordering. The compact dimensions allow use with most stock configurations without interference.
