Love this thing, hasn't failed me yet, good capacity, feeds well (although sometimes requires a lil shake to move the BBs)
If you run an m4 load-out, get one, it's so much nicer than having to store 2-3 of the pistol sized ones.
-M4 mag style for jamming into a spare pouch
-Decent solid construction
-Great little chamber for storing adapter and flip cover is awesome
-It's not perfect, sometimes you have to shake it to get the BBs to go to the feed loop.
-Doesn't have a lock, although the large button and flip-cap for the spigot helps keep it from accidentally feeding.
