A pair of 5mm-compatible accessories based on weapons wielded by characters in
Transformers: Earth Wars. Includes two types of guns often (though not exclusively) used by Gunner type characters: the "kinda like G1 Prowl's gun" type used by characters like Prowl, Powerglide, First Aid, Swoop, and Fireflight, and the "revolver" type used by Sunstreaker, Jazz, Hound, Dustup, and Alpha Bravo.
3mm versions for Legion/Commander/Energon Igniter class Transformers are available
here.
Prize Inside, a seller I highly recommend, has
an alternate, somewhat fancier take on the revolver-type gun.
