Friends don't let friends use Counter Sniper Scopes.
They're junk.
A guy on Sniper's Hide did a very thorough review of one of their scopes, and it read like a comedy of errors. Go to Sniper's Hide and do a search on Counter Sniper. You'll get several hits, but it won't take you long to find the review.
Their business phone is a cell phone.
Their mailing address is a PO Box.
The physical location they gave shows an empty lot on Google Earth.
When you start asking one of them anything that's not on their little Starwars advertisement, they hang up.
They're selling cheap chinese junk. They'll replace your scope for free rather than repair it; they still come out ahead.
Cheap ****.
