Has anyone actually tried something like this? Cost = about $30.00. I remember the government paid something like a billion dollars to develop similar (more advanced tech) for ARs, which is sad and hilarious at the same time. Can you really hold an AR, over even a .22 around a wall and see the dot/target with one of these things? Might make for a fun 'shooting from behind plywood or barrels' toy at the range if so. It says you can shoot directly/normally or from either side.
