Indoor BB target
I have been trying to come up with something for testing my Airsoft guns in my room.
Everything that I have come up with is either really big and ugly / doesn't work very well, or make the BB's ricochet all over my room.
I have tried setting up boxes and having a towel hang down to absorb the impact, and stuffing a 2Liter plastic bottle full of foam and other things.
What have other people come up with and how well do they work?
