For hunting, the ALG Defense ACT is what you seek. They supply 2 sets of springs now. Mine breaks at 4.5 lbs. and still retains mil-spec reliability. Definitely a best buy IMO.

I also run a RRA 2 stage, which is also excellent for the money. It also breaks at 4.5 lbs overall. It may be better for target shooting, but I think I have come to prefer the ACT for hunting.

BTW, ALG = Amy Lynn Geissele......
