About 40yds is the most i would do, rabbits mainly, got a couple of places lined up for a bit of ratting. I have a 4-16 44 original mamba lite on my 95k which i like. Had a look at a compact scope 40mm i thought it was a little heavy for the size of it and the turrets were fairly high. Had a look at a new mamba 4-16-42 which looked nice and slim, turrets were small and light, also has IR on now, i am thinking about getting one. Put it on the hw100 and keep my other mamba on my 95k. Thank you for the reply mate, ATB.
