Description
The FX Mega Magazine (often listed as the FX SS or Side-Shot Mega) is FX Airguns’ high-capacity magazine for its side-loading rifles. In .25 (6.35 mm) it holds 16 pellets or slugs. The body is injection-moulded POM for durability and easy loading, and FX supplies it with a dual lid so it fits both Crown-style rifles (Crown, Dreamline, Maverick, Wildcat MkIII) and Panthera-style rifles (Panthera, Dynamic; King uses the thicker lid). FX lists the maximum ammunition length as 10 mm flat-nose / 11 mm domed, with the Panthera-style lid accepting longer projectiles.
Fitment: FX Crown, Dreamline, Maverick, Wildcat MkIII (original lid), Panthera, Dynamic and King (thicker lid). Dual lid included for Crown-style and Panthera-style rifles.
