Thank´s for the info Rocky Raab.
I´ve just recieved an E-mail from AI in UK and they told me that the short 20” barrel is preferd by most law-enforcement snipers and hunters and would be good out to 600 meters (308W). And the price............... hum! I life in Iceland and if my calculator is not lying then I would have to pay around 6300$ (300 WM) befor shipping and taxes. The basic price is for the rifle with fixed stock, one magazine, Bipod & Butt spacer kit. That’s a bit to much for a student
