Matrix Metal 120rd Mid-Cap Magazine for M4 / M16 Series Airsoft AEG Rifles (Package: Single Magazine)

"Purchased these magazines for a new Classic Army M15A4 that I got, nor will it work for the old style CA M15A4. None of them worked. The magazines will not go fully into the mag well, and when I go to remove them it requires a considerable amount of force to do so. Otherwise the build quality is decent, all metal with a semi-matte black finish. Seem durable but I can not use them with my current AEG. Also take note that in a majority of the other reviews, other players have had to modify these in one way or another.

Pros:
All Metal
Nice Finish

Cons:
Will not work for Classic Army new or old
Others needed to modify to make them work
Extremely tight fit in mag well.
