I recently purchased a Classic Army M15A4 Carbine from airsplat with the M203 long barrel grenade launcher upgrade. Now for starters i'm extremely new to AEG's but i work in a technical field repairing medical equipment so i'm not entirely clueless when it comes to assembling/disassembling a wide array of things so i figured this shouldn't be to difficult of a task, but obviously i'm doing something wrong. The issue i'm having is that after installing the grenade launcher there is absolutely no where to place the battery inside of the top handguard (the battery cable is actually intended to run through the bottom handguard but the barrell mounting bracket for the grenade launcher prevents this). I'll attempt to post 3 pictures to show my problem, if anyone could help me with this it would be much appreciated...i ordered my parts from airsplat.com but needless to say they make no mention of what upgrades or extra parts are needed in order to properly install everything, thanks for the help
Also here are a few links to the gun and grenade launcher that i purchased,
