Cops are some of the cheapest people on the planet, always eyeballing the "just as guud" optic or mount that costs 1/3 as much as a known reliable standard. Then when they need their "Just as Guud" to work, it is all jacked up.
I would cringe when some clown would show up on a call with his personally owned rifle from an agency that allowed them to stick on whatever they wanted. The thought of relying on their equipment to run properly when lives were at stake was not confidence inspiring.
I got tired of trying to convince dudes to not buy Chinese crap, pot metal mounts, airsoft garbage, etc. It drove me nuts. They would ask what to buy, I would make a recommendation, then they would get something out of a Sportsman's Guide catalog that was "
military style"... SMH...
The punchline is, if you need a basic RDO, buy an Aimpoint PRO.
When you need your optic to work, it will actually work and stay zeroed.
