"Howdy, If you're fortunate enough to own a Tokyo Marui GBB M4, these are worth the money. I know $99 per mag is hard to swallow, but if you are gearing up for a single load out, say 6 mags, then buy once, cry once. The difference between these and the TM mags is $40 each, so x6 mags that's only $240 more. These are lighter by almost a half pound each, hold 50 rounds instead of 30, look better, have the fill valve up high on the back of the mag where they don't fill with dirt, and are much easier to load. They also hold more gas. The ease of use and performance is worth that extra bit of cash up front. By the way, the TM Zet System absolutely blows doors on all other GBB platforms, bar none.
