Rear Bag For NRL22 Prone Position

Same bag I use up front, most matches I can get away with only one bag. Currently experimenting with Git-lite fill, and so far don’t feel like I’m giving up much from the heavy fill.
 
 
So personally I have a mini game changer and it covers a lot. If I wanted more of a small handheld rear back, there's the "Taylor Was Here" bag sold on the forums here. The idea being a handheld (with a strap for the hand) one you can grab the butt of the rifle with.

Out of curiosity though, what the current "pain point"? What are you looking to do/accomplish that your current setup doesn't do? That may get a closer answer to your specific need.
