22lr (5.5mm) silencer 1/2" UNF 20

thingiverse

If you want to practice rifle shooting silently, this model is based on my 4.5 mm design. I created and printed this sound suppressor for: 22lr or 5.5mm air rifles. To print it vertically, place the large hole at the top. After printing, simply tap 1/2 '' UNF 20 and use it! The pilot hole is made for a 1/2 '' UNF 20 tap. Tested (in PLA) with 22lr subsonic: slightly noisier than a still Number 5.
