120 BB's Mid-cap QRS magazine for M4/M16 - Black

Good quality build. Ordered two, one bb always remain in one. It's just a minor complain. It's not fit perfectly in my G&G Arp 556. Little bit tight and the mag doesn't lock perfectly.

These magazines are AMAZING. After doing some research online I found these were some of the best M4 mid-caps. They feed high ROF guns, are build like a tank, and very light yet durable. They even have some unlisted features, as listed below. On the bottom of the mag there is a pre-moulded digit for you to fill in with paint. This gives the magazine a number, so you can remember which mag is full and which one is empty. The pattern on the sides provides extra grip, but is also there for reinforcement. These mags have a built in quick draw mechanism to make reloads even faster. Really happy with these mags!
