The H3 was a heavy blaster rifle which was produced before, during and after the Great Galactic War.
H3 came in three main modifications. The basic version, A1, had a very short barrel and was stockless. The long-range modification, A2, was equipped with a standard long barrel, a buttstock and a basic scope. The A3, the most advanced of the three variants, had all the features of the A2 and was also equipped with an advanced targeting scope and rangefinder. H3 was produced in four basic color schemes.
