|$16 for the 42 round magazine is drastically lower than I've seen anywhere else. They are nearly identical to the factory magazine that comes with the A3, except they hold 42 rounds.
I have had no issues with them. They work as well as the one that came with the gun.
42 is an odd count leaving extra rounds in the box. I usually load them to 40 for that reason. Works out better with 200 rounds.|
