Nuprol M4 Metal Mid-Cap Magazine 140R

The Nuprol M4 Mid-Cap Magazine 140R Metal is a metal mid-cap magazine for M4 type replicas and can hold 140bb's in total.

The beauty of this magazine is that through the bottom of this magazine you can also adjust the number of bb's to 30 bb's which is of course perfect for Milsim events. Loosen the screw at the bottom, slide the plastic housing out of the metal construction, slide the switch to the desired capacity and put everything back.

You will need a speedloader to load this magazine with bb's.
