Hi,

I've owned the above gun for a number of years now but it's been mounted as a collectors item for the most. I've got a bit of time off so have decided to service all my mags as some are leaking.

 

Is there anyone familiar with the mag for this gun and how I can remove the valve to oil the seals? I managed to depress the small ball bearing and remove the black plate from the bottom but had no success getting any further, I've slid the plate back on but the ball bearing is still inside so I can even get the plate back off. Any help would be greatly appreciated. 

 

Thanks
