On the .308 Vepr do you have to cut a hole for the trigger or do you just have to drill the plates off like on a .223? Who makes a drop in trigger for a .308? Red Star? I heard you have to do some tweaking to get the G2 hammer to work properly? I am wanting to go with a Drag stock and keep the factory forearm unless there is a free float set up somewhere someone is doing. The factory mags are even fine with me.
