Marushin 15rd CO2 Magazine for Marushin M1 Carbine Airsoft Gas Rifle

"Received my Marushin M-1 Carbine magazine today, Man is it weighty, Has to be the most solidly made C02 magazine ever made. Has to weigh a cool 2-3 lbs. but they function flawlessly which seems to make up for the magazines priceyness. I know these magazines are hard to find, and I'm glad Evike had them in stock. Thanks so much also for the usual quick shipping across the country.
