Question

What caliber would a gun have to be for an airsoft BB to fit in its chamber?

Answer 1

6 mm. There are many newer rifles, and older pistols chambered in various 6 mm or close to 6 mm rounds.

Answer 2

.25 cal.

Answer 3

Airsoft BB's are bigger than normal BB's.

Metal BB's are 4.5mm or .177 cal.

Airsoft BB's are 6mm. So the only guns they fit properly in are Airsoft guns....no others.

Answer 4

there is no caliber that will fit. 6mm airsoft bbs are plastic and will not fit in your barrel

also the light weight of the bbs might damage some guns
