22 Silencer 1/2”UNEF, 32 mm OD
cults3d
This is our standard-size 22 cal silencer with a 1/2”-28 UNEF thread. The silencer dimensions are 150 mm (6") long by 32 mm 1-1/4" diameter. The weight is typically 50-65 grams, depending on filament and slicer settings. This STL has a 1/2"-28 UNEF thread. We also offer a 1/2"-20 UNF version. This STL is released for distributed manufacture free of charge in support of the World Hearing Safety Project. This silencer is designed for air/CO2 weapons up to 22 caliber. Subject to adequate layer adhesion, it may be useable on 22LR rifles and pistols. Due to the constraints of design for FDM it is not the quietest 22 silencer in the world but it is one of the lightest - and for a material cost of about fifty cents, it is one of the least expensive. When we get around to running some MIL-STD-1474D noise suppression tests on this version, we'll publish the results here.
