Another helpful video from Pheas Airsoft that owners of the Double Bell 091 would want to bookmark as this a disassembly of the airsoft gun maintenance and repairs. This is part of the The Double Bell retro series high attention to detail is applied to it. It is made mostly of metal, with a polymer grip, stock, and handguard, it features a working bolt-catch and quick spring change system. The replica comes with a 300 BB capacity hi-cap magazine.
