inexpensive suppressor: ATF registered.

Don't know how many of you guys are into suppressors but my friend Chris at ASA makes an adapter that allows you to use oil cans as a suppressor. It has to be registered with the ATF ($200 tax stamp.) It works great with .22Lr and will work for a limited time with a .223. There is a problem with using it with an AR-15 because the Ar-15 sucks air after each shot. This can cause the filter material to come back into your gun. It's a pain to clean it out after that so I don't recommend it. Other than that it's a cool little gadget. I'm not sure how he came up with the idea but it works well enough that people think it's an air soft gun when he's shooting it on his 10/22.
