I have to say, I am VERY impressed with this scope. It took a few days longer than expected to arrive, but it is Christmas time. This scope is most definately worth the price, delivered to your door for under £20! It would cost that much to buy the mounts alone here in the UK. Also if anyone is wondering, the scope rails are for a 20mm (weaver) mount that features on most airsoft guns. I can't say enough great things about this scope!
