This oil filter suppressor is surprisingly quiet.
YouTuber Hickok45 shares a cheaper alternative to traditional silencers: the oil filter suppressor.
Oil filters can make great suppressors for a .22 rifle. Watch Hickok45 explain the ins and outs of an STP silencer.
This oil filter silencer would be nice for recreationally shooting. The effectiveness of the oil filter is simply surprising. Wonder who thought of this bold and innovative idea?
Potentially, the best part of the setup is the cost break, since the oil filter is the silencing mechanism and only the adaptor and stamp is required for purchase.
