I got a bunch of these for my Scar and they work perfectly. I split the price with my stepbrother so we both got 5 of them and I couldnt be happier with my purchase. Incredibly solid magazines and I don't think i've had one misfire with them yet. They also have a bit higher capacity than msot mid caps.
Plastic to save weight
Cheap deal per mag
They have a slightly higher capacity than msot mid caps ( 20 rounds or so )
Plastic (Some would call it a con)
A bit loose in the mag well, though that could be my gun, easily fixed with some tape
