Our take: This CO2 blowback rifle magazine holds up to 30 rounds (we recommend loading no more than 30) and is fully compatible with WE Tech’s M4 GBB Rifle. The gas magazine’s exterior build and internal parts are constructed out of metal. This not only makes it highly durable but also gives your rifle realistic weight. For perfect feed and fitment every time, this 30-round M4 CO2 magazine by WE is the perfect spare to have on hand.
