Great to get a proper listen to the sniper in isolation! Hopefully this guy does a similar upload for all weapons.
Someone on Waypoint just pointed out that the Splaser has the old UNSC logo, not the post-war one that most things seem to feature. Interesting.
Maybe the rail gun is supposed to be the spartan lasers replacement in the 'UNSC' but you have access to spartan lasers from ones that were left over from the 'forward unto dawn' & that's why it has the old logo... Maybe?
