Kotobukiya completely renews some of its Modeling Support Goods items to celebrate its 15th anniversary! The Burst Railgun appears in place of the Weapon Unit 01 Machine Gun Type 1. Its configuration can be changed from a standard rifle to a barrel-deployment type railgun; two types of gun barrels are included. The A type of gun barrel can extend its length by combination, and the B type has a blade-like shape. The grip is movable to use the weapon as a rifle or a blade, and it also comes with long and short magazines. This item can be used by Frame Arms, Frame Arms Girls, Megami Device, HexaGear and other action kits and figures!
