bad move. getting an underpowered BA to play indoors with AEG's is going to frustrate you and piss you off. even with everyone else on semi only, it's going to be tough. maybe you need to change your choice of sniper rifle to DMR?
looks like you need to find a different team rather than a different gun. keep the AEG. upgrade bits you can afford. eventually you could build an outdoor front end to swap or go balls out and upgrade to an spr or m16 length with the internals to go with it. this could possibly be cheaper than getting a sub par BA and then have to upgrade it to compete with AEG's that will easily out range the stock L96 you want.
