The other week at the range, a guy next to me was shooting his AR.
We got to talking about my Swiss 96/11.
I saw a black bumper stuck to the deflector on his AR.
Asked him about it.
He said he saw it on-line while looking for something else.
Was cheap enough, so he got a kit to try.
It seemed to work well
All the shells were deflected into a small area at the 2:00 position.
No dents on the shells.
Don't shoot much AR's, but I may try them.
