I bought one of these for my S400, Lev off the AGF put me on to these scopes, I bought the 3-15x44
1" tube with ir as you say £400 I think this is a very nice scope, possibly better than the run of the mill Hawke scopes, Sidewinders included, it does have a very fine reticule, which I thought might be a problem in dark areas, but its been ok, plus you can light it up anyway, a couple of guys looked through it, and were very impressed, I think the question is really, would I buy another, and I have to say yes I would, and probably will in the future. Buy it off Uttings, and if you're not satisfied, send it back, but I think you'll like it.
