Return to sender only works some of the time. I researched and tested it myself on guns with it

Add firefly

yo if I see another NLB in this next week of events I'm gonna flip. I rolled 5 of them last from 3 night falls and 2 raids.. it's like Bungie WANTS me to use that shit

Give it at least half the ammo of a Hand Cannon and it would help a lot. Otherwise, increase the damage to make every shot more deadly. Personally, I'd love to see it placed in the special weapons slot with the other snipers or at least have an option to put it there.

Mulligan should be replaced with a head shot kill grant bullet to chamber or missed shot has chance of returning to chamber. Both would be a nice perk which would skip the lever action animation and help push the gun to more user friendly. Disclaimer I like it how it is and I'm not concerned if its changed or not. Those are just my ideas.

More ammo in reserve. Less sway when aiming down the sights. The extra precision damage part of 'The Master' should be switched to either Mulligan or Return to Sender (it's a sniper rifle, it already does a load of precision damage). Mulligan switched to Zen Moment. The second 'ring' of the iron sights should be removed to make them less obnoxious to use. The bolt-action animation should have a speed increase. I can't think of anything else...

RTS would only be worthwhile if it actually PROCCED on a decent basis. But it doesn't. It only proccs once every blue moon, and never when it actually matters, so its batshit -blam!-ing useless. Mulligan is fine, if it has a high enough percent chance, but replacing that, with an even worse percent chance skill is not the way to go about your duties xP. NLB is just a terrible all around weapon. Its greatest value is the trolling value. 'Precision damage increase' ..... Because that is really -blam!-ing worthwhile when playing in crucible, where headshots are 1 hit kills except for the occasional Scorch Shield radiant Skin warlock. ALL of the perks on this weapon are absolute trash. Bonus agility? Faster Reload (And that isn't the rechambering, that is the actual RELOAD)? 'Incredibly Fast Aiming'? 'THE MASTER'? Every single one of them are absolutely shite on it. I'll take Icebreaker any day, and THEN some. I'd sooner take my LDR 5001 with Armor Piercing, Firefly and Double Down (Occasionally on spawn spawn with extra ammo (typically gives me around 2 bonus clips (4 rounds)) and Skip Rounds (I never use them, or Agility bonus, its always Armor Piercing). This weapon needs an insane overhaul. The only reason to actually use it is to be a troll. Nothing like watching someone score a headshot on you with an ironsight sniper rifle and then slowly rechamber another round like he REALLY doesn't want to be there.

Needs another perk that increases your agility after a kill or something to make it better for Crucible.

That's cool, any kind of buff would be appreciated. And btw return to sender is any kill with the gun returns bullets to mag not just precision.

Maybe something like the white nail perk on black hammer. Maybe have it where 3 consecutive precision kills puts one or two bullets back into the clip directly.

Both perks are equally bad though...
