||These mags are awesome! The perfect balance between holding a lot of rounds and that awful rattle you get with high caps. Since the bb's don't feed from a reservoir, all bb's are being compressed by the spring inside the mag which is great for added realism.
1. Feed very well
2. Solid construction
3. Fits almost any m4 style gun
4. Feeds upside down
5. No noise when trying to sneak up on people
6. No winding!
None, its the holy grail of MilSim M4 mags
