Fallout 4 Best Starting Weapons! (NEW) 2 powerful sniper rifles 

IMPORTANT: Save before heading over there. if the laser rifle isn't by the bed, quit/reload and try again. Took me two tries.
Haven't seen these weapons mentioned anywhere in reference to getting powerful guns right at the start of the game, so I thought I'd make a quick video showing you guys where to find them. While technically you could rush right over to get these at the start, it's easier to simply get Dogmeat, do the Concord mission to rescue Preston, then talk to him in Sanctuary so he sends you to Tenpines Bluff.
