Umarex 40rd Magazine for VFC H&K MP7 Navy Airsoft SMG GBB Rifles

"I've been using my mags for a while the only problem I've had was the feeding lips which since then fixed itself.

"Besides the price point, they're good mags. I bought two extra mags when I had bought the VFC Navy version of the MP7 so it was quite expensive, but worth it since I love the MP7 and have always wanted a 1:1 Scale version in GBB and I've been having a blast using it at games.

These mags being full size as well pretty much weigh the same as the Navy MP7 so it ends up doubling the weight of the gun when fully loaded. They do feel nice and sturdy and feed well if loaded in a proper zig-zag, if you even have one gap in the pattern it'll cause the gun to misfeed and cause the next bb to get stuck between the bolt and the feeding lip on the mag.

You can go through roughly 80 rds ( depending on weather conditions ) if you stick to using Semi-Auto. These mags hold gas well. I actually managed 3 1/2 uses on one mag before having to refill granted it was hot the day I had used it.

Other than the slight feeding issue if not loaded properly, I'd say these mags are worth the price though I wouldn't buy alot of these unless you know how to maintain them properly. I manage with just three mags in total though I'll be picking up one more since I have a triple MP7 mag pouch and one is always empty.

"Great magazines, super snappy, hard kick, and can hold the gas for about 2 magazines worth IN THE WINTER (46F-60F).
Can’t wait to see what they do in summer.

Pros:
-Holds gas well, even with full auto
- Nice sleek feel
-Good Feeding, not many issues
-Snappy
-Heavy

Cons:
-I did receive one with a broken baseplate, which kind of made the whole thing inoperable. The side of the baseplate was chipped off, meaning the baseplate couldn’t hold on to the mag too well, and would fling off, sending the spring and piece flying. But the mag still worked fine, and I will either return it or get my friend to 3D Print a baseplate for me.
