I have a TRG-22-308, and a TRG-42-338L. The 42's are identical in both 300, and 338L. I do plan on a 300 as soon as money comes my way. These are one of the best out of the box rifles I have ever used. What more do you want out of a rifle that is used as a sniper rifle for over a dozen countries.
It has a match grade adjustable trigger, full adjustable stock, 60 deg. bolt throw. Only bad part of this rifle is everything is extra, scope base, muzzle break, back up match sights, and so on. i have both of mine set up exactly.
Factory muzzle break, Warne scope rail, Leupold MK4 8.5-25x50 TMR scopes with MK4 rings. I went with the Harris bi-pod adapter and Harris BR bi-pod. Both rifles can and do shoot 5/8" or less 10 shot groups for me. Highly recomend these rifles.
