We recently had a shooting session at the Contra Costa County, CA Sheriff's range. We fired a variety of calibers totaling 163 shots. There were 2 misreads. These were a result of over-compensation by the shooter. The shooter (me) was shooting an M-16. I shot too high out of fear of killing the light screen.
This particular PVM-21 has now re-corded over 1000 shots in a variety of light conditions. The above mentioned misreads are the only ones encountered. I have shot 2 different .177 air guns, a .223 bolt gun, AR-15, 6.5x55mm bolt gun, .308 bolt gun, .308 semi-auto, 9mm pistol and a .45 ACP. Two glitches (operator induced) in 1000 shots. Not a bad record.
It's Here!!
