I have an Air Arms Pro Sport in .177 and want to fit a silencer. Has it got to be in .177? I fitted a .22 one and it made no difference. I know it has one already inside the barrel shroud, but I wanted it made even quieter. Adrian
Hello Adrian. Assuming that the silencer you tried was of good quality, I’m pretty sure that you’ll never be able to hear the difference between a .177 silencer and a .22 one. Only precision decibel meters can measure such things. If you’d like your spring-piston gun to be quieter, you might want to consider having the action tuned by a professional gunsmith. The noise from the action of even a high-quality springer can often be muted, as Charlie Portlock found out in his article this month. Ed.
Most airgun silencers are made in .22 but work just as well for .177
