Magan to Dangan o Tsukatte Isekai o Buchinuku! Description: Ops. Athal, a young man who lost his life in an unfortunate case, receives three special powers from God and reincarnates into a different world. The strongest gun, the ability to create bullets freely, and the ability to see everything called “magic eyes”. Atal, who is the only gunner in this world, casts himself into a supreme supple adventurer guild with the beastman girl Caro who is rescued from slavery and takes on Atal. The sniper’s up-and-coming hero who eliminates any enemy with a single blow, opening from here. Manga RAW elsewhere.
For now there is only one chapter, but I looked at the manga pages and loved the first ones. On another note, the MC reincarnates as an adult, if I got it right. BTW, MangaDex hosts the translation of the manga. There are 3 chapters translated so far (2~3 months between chapters).
lol the translator still puts the title as Megan. Oh well, they've dropped it after first chapter so I'm sure nobody will even notice the mistake.
