Help needed please. I am looking for a day sac in the region of 30 - 40 litres that I can use on my TA training. In particular I am looking for a day sac that can take the two spare barrels of a GPMG, preferably on the outside in a sort of pole pocket, as I am re-roling as a GPMG gunner. Also I have seen on the 'Airbourne' webbing rigs the velcro closure ammo pouches and I am having no luck finding them as a replacement for my own ammo pouches without buying a complete bespoke set of webbing. Can anyone help as to either question? Any help appreciated.
