I bought one of these UTG Bugbuster's for use on my 110 , and I cant find anything bad to say about it .
For the money , with QD mounts , flip up caps ,a sun shade and a cross hair and mill dots that don't vanish when you use a red torch
its just good value.
The IR isn't set on clicks , its just variable from very dim to too bright.
It has a good field of view , and even in fading light performs very well.

For £85.00 No Complaints from me .
