Interesting way to store items in a flashlight.

[Great-Kazoo]

Alright so is the concept here buy a Mag-light, buy these storage cups, drill them out to create baffles and then manufacture your own endcaps to use the flashlight body as a suppressor? if so what is the reference to "freeze plugs"? After obtaining the appropriate tax stamp of course.

Freeze plugs are one of the many items used to complete a solvent trap. With the link provided, among many discussions on line.

People have used FP's shot glasses even untold hours on milling machines and lathes, in search that desirable finished item. My next one, once approved will probably be made with flat washers, why not.

I had seen the references to solvent traps (Caps to screw on oil filters, soda bottles etc...) and was familiar with them. I had even seen them being sold at the gun show a couple of years ago.

Wait - you could store batteries in them.
