S&T Sterling Mk7 Airsoft AEG Submachine Gun

"This is a pretty cool gun, maybe not quite worth the $375 I paid for it but it shoots fairly accurately and the suppressor surpresses a little of the sound. It's extremely and there's only one strappointr on the the gun which also serves as the battery cover, speaking of the battery cover this is the biggest issue i have with this gun, a 7.4 micro lipo like i use in the barrel of my echo gat won't fit in fact neither will 11.1 lipo or even a standard Nimh. So basically unless you track down the smallest lipo in history the battery covery won't fit back on the gun so i have to tape it to use it during game play not cool at all why would they make a gun like that. Also despite what the ad and text say there is no barrell extension that comes with this gun suppressor yes extension no. So that wasn't very cool. Other these gripes 3 days in this gun is ok.
