stock, haven't seen any other hoppers avail. for the a5.
comp-air a5, flatline w/ e-grip
High profile, flimsyness, speed of reloading.
Personally I like the stock hopper better primarally because of how rough i am on equiptment and my preferance of continous fire while reloading. I have also been pegged right in the hopper many times and the high profile proves to be a large target. However this hopper may be ideal for someone who doesn't bring any pods onto the feild/ woods. The extra capacity for the one hopper full player may prove to be very atvantagous. It's just not for me, tipically I bring from 600-900 rounds out with me. It is not as durrable as the stock hopper - lid keeps falling off, (i'm a little rough on my equpment), and the hopper would rotate in the cyclone feed at times threatening to fall off completley. its profile is a little higher than stock which is one of the key benifits of having an a5. also the speed of loading with a fresh 150 takes a little longer due to the amount of effort required to ensure the lid is properly seated when closed. i also found that because of the angle of the lid you have to tip the marker down slightly in order to reload. typically i perfer to reload while continously firing. this proves difficult with the 240 rnd hopper.
Great for a 1 hopper full player. Bad if you're rough on your equiptment, worried by reload time, or about a higher profile.
