Good all around. Main issue is the 20 round capacity...but it's perfect for mil sim or if ur more accurate and like to try to play as legit to the real deal as possible. Nice construction, easy to load, and fit perfectly into the mag as they should. These mags do seam a little weaker than their 40 round counterpart but still very good.
Easy to reload
Fit perfectly in gun
Small size makes them fit anywhere in a vest or holster or even pockets
On the cheaper end for gbb mags. May be do to round capacity however
Seem to be less durable then 40 round counterpart. I've had 1 40 round mags for a few months now and got 3 20 rounds a few months ago. My 40 round is scratched to death from loading and dropping and storing etc and still works perfectly fine. However, out of my 3 20 rounds, one of the. Already has some object rattling around in side of them. Almost sounds like a piece of plastic from the lip or something. Mag still fires fine but just something I've noticed
Mag capacity. But there low cap gbb mags so u can't expect anything more
