I put a Timney single stage 3# in my Rock River, and it is fantastic. Rock River’s triggers are nice, but don’t begin to compare to my Timney. Wanted a single stage, as thats what I hunt with. Also put an adjustable single stage in my sons build. If I remember right, it was a Riflebasix,but could be wrong on the name, it was apx $250, my Timney was about $225. Really like both of them. There are alot of good drop in triggers out there, and you really don’t need to spend over $200 any more. Velocity had some safety issues early on, but I think they have corrected that now. Really what you need to decide, is do you want a single stage or two stage. I have experience with both and prefer single for hunting, and two stage for serious target shooting, but have no problem using a single stage for both.
