Hi there
I have tried the Marui Standard, High and Mid cap in it. all work well.
In fact apart from the cyma mag being plastic and creating a wierd gap at the top where it hits the reciver, id say that the Cyma ones rock considering that Keith at RSOV is selling em for 10.99 a pair (ordered 4 i have).
When those arrive my rigger pauches and Sten gun mag pouch (of ebay) will be full of low caps.
So Now i have to wait for the next big WW2 event
then die Nazi pigdogs
Unless i decide to go with the Agm MP40, then die allied scum
sigh so many (or mayb too many but how ca
