the 510 on the magma is slightly longer than most 510s which is why it isn't sitting flush on some
mods. it's longer than my zenith v2 and tugboat clones which both 510s on those are the same length.
btw my magma is made by infinite and it's pretty perfect, very well made. showed it to my friend who had to ask again, with major suspicion, if it really was a CLONE because it looked exactly like the authentic he checked out at the
shop earlier in the day lol
