Mk1 with a doubled and adapter, secondhand cost me no more than £300, and to be fair its great value, have a t20 extra ir and I can easily see and identify bunnies at 150 yards plus, I had to fiddle a little bit with the set up, mounts, opened out the lense cap to 35mm and leave it on both day and night but its pretty effective on my hmr, for the cost I think its a good value way to get into NV, tyrouble is like everything it becomes quite addictive and to step up in spec will cost a little bit more
