This one's a bit heavy with the Can and rem var contour barrel, but the HTG could carry a lighter stick (something in the 8-9lbs range)
The problem with the HTG is comb height. My rifle (pictured) has to have the check peice adjusted all the way up for me. I have to lower it to remove the bolt. My A3 is much better. I got it for a heavy build; It doesn't have the comb issue. I don't know how light you could go with the A3.
I also really like the McM. Rem Varmint Stock. Real nice feel for a mid weight hunter.
