here is a Pouch for 5 HDR 50 cylinders. that can be mounted on the molle system.
to load it slide the top open. place the 5 cylinder in there. and make sure they don't flip over.
than you can close the lid. and your ready.
this van be handled with 1 hand. use your thump to slide the bottom bar up. and use your other fingers to grab the cylinder out.
now do you have place to insert the empty cylinder from your revolver. this one will be added on the top part. and should unlock very easy by just trying to slide it in.
I designed this pouch so it would be economic with your molle space for the amount of "mags" you could bring with you. and keep the cylinders and paint out of the elements.
Shell: Wall line count: 4
you will only need 1 spring for it to work, 24mm in length and 4mm in diameter
