I am never going to get off my butt to buy a suppressor.  However, this would satisfy my desire for a backyard shooting rig if it works.

 

I'm thinking a pvc pipe and sound proofing foam with some plexi glass. I just need something to quietly test fire my experimental .22 pistols and rifles.

Interesting, seems simple enough to make something similar.

It ceases to amaze me what will come out next in the gun world.  There are many of products out there for a dude with a gun.

The store is closed for maintenance

How much does it cost?
I don't think it would do much. It might reduce the sound of a .22 some, but the sound is coming out of the end of the barrel and the box is open on that end. Maybe if it was 10 feet long.
But maybe I’m wrong; I’m certainly no acoustics expert.

I saw a similar idea years ago using old tires.

I can't find it, someone might have pulled the video for a reason, it sure didn't seem quite at all when I seen it yrs ago, they were using 115# regular rounds they should be using 147# subsonic rounds..LOL
