We have had several customers ask how to fit the batteries into the TSD-Tactical Gen-II AEG model SR36 Carbine. To clear up any confusion and alleviate any potential frustration here are some tips and a couple pictures demonstrating how to get the battery to fit.
The best way to keep the battery in place is to use rubber bands, string, or a zip-tie to hold it to the barrel. Once the battery is in place you can put the cover back on and start using the gun.
