7.62x51mm NATO, aka .308 Winchester with detachable magazine and synthetic stock.
I have a Bushnell Sportsman 3-9X mounted on it, with a bipod and extra sling attachments, and maybe i'll camo it with something..
I bedded the stock with Acraglas and made the barrel a free-floater (Remington uses the principle where they support the barrel from two points; the receiver and the tip of the stock touching the barrel) The bedding was necessary because the factory stock had so much flex in it that it would affect the accuracy. The whole package including the bedding compound cost about 750€
E: oh and the rounds i'm using will be Sako Range, which come in 50 rnd boxes, cost me 52€. 7.62, Full Metal Jacket (see what i did there?), bullet weight 8grams
