Description

The all-new KWA MS magazine line, available in either cutoff (MS120c) or standard (MS120) 3-packs, lets you customize your AEG loadout like never before! The MS line is made with KWA’s ultra-durable fiber polymer, giving you lightweight, rugged, and reliable mags for CQB or MilSim games. The new mock- window, which mimics brass 5.56 rounds, adds some style to your mag pouch, while the dot-matrix ID panel lets you mark your mags with numbers or initials for easy identification. Handling the MS mags is never a problem thanks to unique front and rear grip lines that ensure that you never lose your grip. These MS120c mags also let you change BB capacity from a realistic 30 rounds to 120 with the flick of a switch, which is perfect for LE/Military training scenarios.

No plastic seal that normally comes taped over the circle ball ejector. Some type of hair or dirt is all over ALL 3 mags. I returned my first order, purchased a second order. Arrived exactly the same, no seal and some weird fuzzy looking dirt, even check second picture, the 30/120 switch has been moved. These are not new, their used returns most likely. Their whole batch are used being sold as brand new. Ridiculous. ... show more

    • Title: Disappointing Performance – Not Worth the Hassle
Rating: ★★☆☆☆ I was really excited to try the KWA Variable Mag for my VM4A1 2.5, but unfortunately, it didn’t live up to expectations. The magazines I received appeared to be used and showed significant issues right out of the box. Feeding Issues: The mag failed to feed BBs correctly and often wouldn’t feed unless I applied additional bottom pressure into the magazine well. This extra step interrupts the flow of play and makes the magazine unreliable in critical moments. Compatibility Problems: Despite being advertised for use with the KWA VM4A1 2.5 cutoff, the Variable Mag did not work seamlessly with my gun. The inconsistent feeding and the need for manual pressure were constant frustrations. It’s worth noting that while the stock variable magazine worked fine, the ones with the imitation brass bullets did not perform as expected. Overall Impression: While the idea behind a dual-capacity magazine is interesting, the execution in this case falls short. Receiving used magazines with persistent feeding issues has left me disappointed. I expected a product that would enhance my gameplay, not one that requires constant adjustments and extra effort to function. In its current state, I can’t recommend the KWA Variable Mag unless KWA significantly improves its reliability and quality control on these imitation brass bullet versions. ... show more

    • Perfectly works with my RM4-a1 ERG
It had some fibers on it from the packaging but other than that they work perfectly and have a very nice weight and feel to them!

    • Sent Different Clips
Not all the clips sent were the same. Two were the ones that were advertised while the 3rd one was completely different. Unfortunately it didn't fit.

    • Nothing but issues
These are terrible. I thought I was buying good mags....they're not at all. Do not feed properly. Throwing these away.

    • Feeding issues
They just dont feed right. I have a kwa t10 ronin, it comes with the ms120 magazine with the gun, that mag fed great! I actuslly bought these by mistake, realized after that these are the ms120c, but they are still kwa and ultimately look nearly identical to my factory mag, but all three have feeding issues. A drop of silicone oil helped, but i still have miss feeds pretty regular, i even tried the velcro trick in the mag well, helps, but still misses. Ordered some ms120 instead ... show more
