The second location that could have a Sniper Rifle is the Red Rocket Mega Stop, located northeast of Sunnytop Ski Lanes. Not sure if they were the first to find it, but their video helped me locate this weapon. Credit to Karpo Musick for this location. Be cautious in this area, as there are several enemies surrounding this location, and some of them are rocking out at level 50.
This appears to be a guaranteed spawn for a Combat Rifle with a scope on it. Look for the large structures that used to support the monorail and, more specifically, one that has stairs leading to the top. This is in the southeast part of the map.
The first Sniper Rifle location is just east of Watoga at the Flooded Trainyard. However, with the help of some YouTubers, I’ve put together a few locations that, if checked repeatedly, are sure to score players their very of Fallout 76 Sniper Rifle. For starters, I’ve yet to find any Legendary Sniper Rifles, not that one couldn’t drop randomly, and furthermore, most loot is randomized at least a little, so where I find a Sniper Rifle, someone else might get a Board. Turns out, getting a long-range weapon like this is no easy task post-apocalyptic West Virginia. After a couple dozen hours in Fallout 76, I finally got tired of waiting for a Sniper Rifle to drop randomly and decided to make acquiring one my goal.
