Batterie won't fit.
 

I have a CA slr105 and recently bought myself a 9.6v 3600mah battery, problem is that the battery won't fit into the stock. I'm missing about 1 inch for everything to fit and really don't want to shim the inside of my stock to fit it properly. I was wondering if there was any extended but plates that could cover the rest of my battery? (no battery pouches either.)

No, Unless you have one custom made, It will not fit. Ive only seen 8.4v Fit inside Full stocks personally. 9.6v is 1 additional cell, which is why it doesnt fit.

Either lose the 9.6 and get an 8.4 or get the AK Stick Batts (fits in battery tray under your bolt), lipos or minis.
