rubber sleeve dimensions for Magpul pistol grip

Can anyone get me the dimensions and what guys use on the rubber sleeve over the Moe pistol grip as well as the Tango down stubby vertical grip.

Bicycle inner tube, or a Hogue Handy-All…

+1 for the bike inner tube. It’s cheep;) I use a size 26in. x 1.9-2.125in.
