Nuprol PMC Sniper Open Mag Pouch V2 (3 Colours)
The Open Mag pouch gives quick access to your magazines when needed but also excellent retention so it doesn't come out when you don't want it too. Dual moulded MOLLE straps attach it to your rig on the rear and the front has a single strap moulded MOLLE loops allowing you to add a extra pouch. Also comes with a belt adapter.
Fits large style sniper rifle mags such as the Ares Striker.
