Identifying optics
 

So I was doing a bit of research for a thing I'm writing, and as part of that I'm trying to work out what optic is fitted to this MP5SF:

My current thought is that it's a Bushnell 1x28 scope, but I thought I could do with getting a second opinion from people a bit more in the know.

Yep, that looks like exactly what it is. The logo is too small to see, but the fact that it has a small top turret, a rather larger turret on the side, and just the overall shape gives it away.
