I just bought a DPMS LR308B, pretty basic model, 18" bull, flattop, crappy standard trigger. First two things are scope and trigger. Suggestions on trigger would be appreciated. Scope will probably be a Vortex since I have had great experience with them and can get them very cheap. Either a Viper 6.5-20X or a PST 4-16X. (May take the 6.5-20 off my RRA Varminter and use that and go down a little in magnification on that one, 20X may be a bit much for .223) Any thoughts are appreciated.
