Ive been using the ns200 for five months now on my sub 12ft lb pcp, rimmy and fac air. Its a cracking piece of kit! Ive made a few mods to it which a lot of other ns users have also started to do. Ive got the small lightweight battery and a Cobra Merlin DSA to replace the supplied rubber jobbies.
Ive shot rabbits to 80yds+ at night and spotted them at 150yds+ i love the aystem as its so easy to interchange between rifles.
