Looks like rise of iron logo for D1 guns from y3 lol

Since that seems to be the og exotic catalyst image, it seems to be a visual bug. No idea how or why its happening but cool nonetheless

It has the seal of approval of the iron lords.

It’s seems to be some sort of UI bug with the Elemental weapon type display when viewed in the Vault. Per your above picture you have two Braytech Werewolf autorifles and two Tranquility snipers, but only one of each have that icon. Now look at the far left of the second line. Both of your Breachlight sidearms have an Arc icon shown, even though Breachlight is a [b]Kinetic[/b] weapon. I have not been able to replicate the Hammer icon, but after reading this post I [i]have[/i] been able to replicate the issue with Kinetic weapons in my vault displaying Elemental symbols when holding the left trigger... If you look at a page of your vault that has armor and then flip to a page with kinetic weapons and hold the left trigger, the elemental affinity tied to those armor pieces will be displayed on those kinetic weapons. As an example... ____________ I only have 69 items in my vault (meaning the first page is filled) with the first two lines of my first page mostly taken up by Kinetic weapons. My second page, meanwhile, has an Blast Battue (Arc), followed by [b]eleven[/b] armor pieces, a used toothbrush, the three useless holiday “gifts”, and three stacks of 999 mod components. Starting on page one and holding the L2 button, my items all display normally. Flipping to my second page then back to my first and holding the L2 button results in my first Kinetic weapon (which shares the same slot on the second page as my Blast Battue) displaying normally. [i]The following eleven [u]Kinetic[/u] weapons then display an elemental icon that matches the elemental affinities of the armor pieces on my second page.[/i] The following seven Kinetic weapons on my first page (that share corresponding second page slots with non-armor inventory items) again display normally. ____________ As I said, I have not been able to replicate the Hammer icon issue, but my vault is clearly not as full as yours (as the included picture suggests you have ten pages of gear stored). Still, I would imagine it is a similar issue. You should flip to later pages of your vault and see if those Hammer icons show up on anything that otherwise makes sense (perhaps Black Armory weapons with Obsidian Accelerators applied to them?). And I would suggest moving this topic to the Help section if possible, so that this display issue can be addressed at some point. [i]note: edited for clarity[/i] (΄◉◞౪◟◉｀)

2 things come to mind. Either its fully masterworked (which kinda doesnt make sence since the icon will have a gold border around it) or its a currated roll

If you use it it'll smash your face

I think it means it has 2 perk options?

Huh I've seen that before, but never payed much attention to it. Could be that it's a curated roll back before they dropped full masterworked

Pinnacle drop?

Maybe You can’t touch this Da da da da

Those happen to be the favorite rolls that MC uses while while playing! You are not allowed to touch them.

Tried replicating it, saw no hammer icon. Not sure what it could mean, but I'm tempted to say it's a visual bug. If you look at the left side of the second row, it's saying you have 2 Breachlights that deal Arc damage instead of Kinetic.

Hmm interesting
