We show that massless fields with large abelian charges (up to at least q= 21) can be constructed in 6D F-theory models with a U (1) gauge group. To show this, we explicitly construct F-theory Weierstrass models with nonabelian gauge groups that can be broken to U (1) theories with a variety of large charges. Determining the maximum abelian charge allowed in such a theory is key to eliminating what seems currently to be an infinite swampland of apparently consistent U (1) supergravity theories with large charges.
