Excerpt from "'Should I Buy It?' – Universal Remote & Other Exotics"
As a primary-slot Shotgun, Universal Remote is a special snowflake in Destiny. It's one of only three primary-slot Special Weapons, along with Vex Mythoclast (Fusion).
Universal Remote's greatest strength is, arguably, your ability to equip a Sniper Rifle while still covering short range easily. Snipe distant enemies (Sniper) or blast 'em close up (Universal Remote). Medium range? ...that's what tactical retreats and teammates are for! But really, the key to UR's value is that engage distance versatility.
One great upside: you don't need Special Ammo! Only Shotgun not to suffer from PVP Special Ammo scarcity.
It's namesake talent Universal Remote "greatly increases" Range and precision damage while aiming. It doesn't shine in any particular stat, and qualifies as a moderate-Impact shotgun. Universal Remote excels at the furthest end of short range in PVP. Out of reach from other Shotguns, but just close enough to be effective.
Ever since the +100% buff to Shotgun damage against non-Guardians, Universal Remote is great for fun & mayhem in PVE. Unfortunately, it's stats (and multiple Shotgun nerfs) have left Universal Remote a middling PVP choice for most Guardians. It can definitely serve you well, but it may not hold up for tough matches. Temper your expectations accordingly.
