I've had a leapers 3-9x40mm armored scope from marstar for a couple of years. It worked great for about a year and a half, nice (not great, but nice) glass and I particularly liked the very fine mil-dot reticle. My M14 was very accurate with it (3/4" groups) and it held zero perfectly; M14's having a reputation as being hard on scopes. After about a year and a half on top of my M14, the scoped rifle got put on a chair that fell over and the thing fell right on the eyepiece of the scope. After that I couldn't get good focus on high end magnification. I sent it in (to USA) for repairs under warranty, but it still cost me $45 in shipping and at the border (Yeah, the dickheads at customs charged me for my own scope, even though it was clearly marked warranty repair). The Leapers people were fast and courteous with me, which I appreciated.
Overall I'd reccomend these scopes to people on a budget, but do be prepared to send them to the USA for warranty work. Be aware though that if you pay $100 for a scope your getting a $100 scope and you just can't get past it.
