I made up a few of these and will make more if there is an interest. They are made from grade 9 titanium and and should outlast any light you own. Caps fit snug and are fast to remove. Rubber seal in bottom so there is no metal to metal contact with the terminals. Single and double holders will fit inside a magpul grip. Compact and lightweight. I only have a few right now so email me for availability.
Shipping is $6 for 1-5
Single holder $22
Tube are .75" 3/4" diameter
Caps are .875" 7/8" diameter
Does anyone know if they will fit the ACS stock?
