M12 308 Winchester, designated M12 for year put into production.
The most comfortable rifle you will ever shoot, weighs 18 lbs. so you can shoot all day without fatigue.
A truly stable platform, with pivoting bipod that locks to keep you level on any terrain. Legs lock with a barrel nut and the plateform is tight and true, no wobbiling. If your rifle is not level you cannot be accurate at long distance.
Note the big thick Buttpad, this is the Cadillac of 308 Winchester Rifles.
