So this probably already has been done or exists...
Mirage is kind of really a pain in the ass. Especially with a silencer. After about 10-20 shots through a can you can’t see shit outside a 300 yards or so. A suppressor cover just delays the inevitable a little bit at the cost of potentially overheating your silencer.
What if you offset the scope like 2-3” off the rifle to look through the optic with your other eye? Like a big offset scope mount. Same cheekweld, just use your other eye.
Horizontal offset would be no big deal; set the horizontal cross at like 500 yards and the horizontal error would be less than 2-3” all the way to 1000 yards. Even then, it’s just a geometric variable you can build into your dope and dial in... it’d be less correction than even just spin drift induces. Basically lateral offset is a ballistic nothing burger.
But you’d be way off the barrel/suppressor centerline. Optical center would be well over 1+ suppressor diameters and 2-3 barrel diameters. No heat mirage.
Has this been done?
If not, why not?
