All that aside, with a bullet hole through the side it WOULD have allowed light into and onto the optical path and this WOULD cause light aberration and cause a fuzzy or hazy picture. That's why we also do a light transmission test. That;'s also the reason why the insides are matt black. That's also the reason why there's such a thing as a stop-down tube.........
It might be tough but it'd have been unserviceable as a sniper type telescope thereafter
