your not going to really find one. if you get the one with the compartments they are for small batteries. not much if any room in there.
ive got a old alice style cleaning kit i just keep in my gear bag mainly so i always have a metal cleaning rod sections for dislodging bore obstructions. all you really need is a bottle of lubricant (i use non detergent 30w motor oil) and a rag. just something to knock the crud off if that. if i need to do a deep cleaning its going to really take more than a simple kit that fits in a butt stock.
i use a magpul acs-l i keep a back up pin set and fire control group in the compartment soaked in oil and wrapped in a baggy.
