Anyone know where I can find a wire or cable for a bore brush that is compact enough to fit inside the AR grip?.
I have an Otis kit, but those cables are really designed to be folded that compactly.

On the other hand, I think I just found a different version than Otis makes specifically for the AR grip.

So you're saying that you have this OTIS kit but don't like it?

I can fit a bore snake, some 2032s, go juice packet, and a hexadecimal wrench in an moe grip.

But that's not what you asked

No, I have their other kit and it wont fit.  I just recently discovered their "grip" kit as I started looking for other options.  What prompted me to post was looking at the Samson grip kit and its pull wire and brush.  Nice kit, but I didnt really want to spend $100.  Actually, now that Ive done a bit of searching, Otis sells spare parts including the cables for the grip kits.  Thats all I really wanted, just the cable thats short enough to fit in the grip.  Link

Why would you want to put that on the gun...

keep a small cleaning kit (I use a GI Issue) in an outer pocket of the case for my rifle. It only gets used in Emergencies.
