I am a half-orc monk at level 14. I am using a homebrew gun called "the demon of powder", which has 6 charges that it expends as ammunition instead of regular bullets. My stats are 14 20 14 8 15 10 in order.
The description of the weapon says I get +5 to both hit and damage rolls, but on dndbeyond it says I have +6 to hit and 2d8+6 for damage. My DM said that the regular damage for this weapon is 2d8.
I'm very confused where dndbeyond is getting the bonuses of +6 from.
Additionally, I am wondering if I should manually add in the +5 to hit from the description or if it is already included?

I do not have proficiency with guns, although the DM has stated that for the sake of the story I am automatically able to use the gun to its fullest potential. The equivalent story-related thing closest to gun proficiency is that it requires attunement.
