New from new Nuprol is this selectable 20 or 125 mid cap magazine for all AEG's that take a TM standard M4 magazine
These magazine allow the user to switch between having 30 or 140rds in the magazine which is great for those hard core players that want a true MilSim experience without having to buy another set of real caps.
Metal construction these mags will take the knocks and dents when out in the field.
