From CYMA we have a Magazine for CM701 Series Snipers.
The Magazine
This is a VSR-10 Style magazine for CM701 Series Sniper Rifles. It has a 30 round capacity and is constructed from polymer with metal components. It is loaded via speed loader through the feed tube of the magazine.
Compatibility
This magazine is designed for CYMA’s CM701 Series Snipers but it may also be compatible with other VSR-10 Spec Snipers from other manufactures such as Tokyo Marui, However modification to the magazine or magazine well maybe required.
