Bought a used model 10 308 FCP-SR from a pawnshop the other day, got it set up with a Vortex Viper HS-T scope and took it out to the property to shoot.
Shoots great, at 100 yards I can get sub MOA groups even though I suck at rifle shooting but one thing I noticed is the accu-trigger is set extremely light, I don't have a trigger scale but I estimate under 3 lbs (lighter than the ascu-trigger on my dads 17 HMR or the accu-trigger style trigger on my marlin .22).

Is the factory trigger able to be adjusted that light or did the previous owner possibly swap springs?

Also is there a place I can get the manual for my rifle? It's the older model 10 that takes the accuracy international magazines.
