I would like some advice on what dedicated NV Scope to get. I was looking at the NITESITE but have decided I want a dedicated one. I like the look of the Pulsar N550 but I think I will only have £500 to spend. The second hand price on the N550 might come down now the N750 is out and some might want to move up but if not what would you suggest. It will be on a CZ 452 .22lr rifle.
