Keeps stinky solvents from getting all over. Perfect for when using a spray can of solvent. Outer threads are 13/16-16 for most oil filters including the Chevy 350 filter. The one shown is a Napa 37202.
anyone report him?
Its not an NFA item until you put an oil filter on it, get it engraved and do the paperwork.
Im tempted to buy one, but despite what I just said, it kind of scares me.
Edit: Note that it doesn't thread onto the end of the barrel, I doubt it would stay put.
So... uh.... this is some sort of makeshift silencer, or am I misunderstanding?
