I Bought a covert in .308, the barrel is slightly longer than the guard. Its short enough I can put it in a back pack if I need. But I put the .338 barrel in it and have a slightly lighter rifle than if you were to get the regular chassis. I can't tell you which is better. But I love my SRS. Im probably going to pick up a .65cm barrel soon, to keep trigger time cost effective. Also, i've never shot any other really high $$ rifles, or customs. But the SRS trigger is far better than any others I've used.
