Do believe the Viper asked about is one a range buddy received a week or so ago and I was at range with him first time he tried it. At 24X his Viper was fuzzy/blurry across the entire lens. Dial it back to around 21/22 power, perfectly clear, edge to edge. Not that I could try anything different than what he'd tried, but sat down with the scope and played around with its adjustments. Just confirmed what he'd found. Shot with him this morning, asked him if he'd returned the Viper. Nope, I'll sell it to Steve.....one of his shooting buddies at another private range, a range the present owner of the Viper is President.
