Oil Filter Adapter for AR-15

Oil filter adapter for AR-15 that enables you to use an oil filter as a silencer.

Why buy an expensive silencer when you can use an oil filter adapter? Construction of the filter is very similar to that of a simple silencer, but without a hole. You can easily make a hole with the first shot; the bullet will penetrate the filter easily and will hit the target on distances of up to 30 meters.
