my friend just had the oppertunity of field testing this gun last night, it was awesome! the red dot sight he bought for it (NC star off of ASGI) made it TOTALLY acurate and this thing, the rate of fire is up the butt! it shoots very very fast and the battery it came with was very good, the gun probably has at least 17rpm. i'd say buy this gun if you want a really good secondary to keep those enemies off! =D>
