MAB (Modular Ammo Binder)
When it comes to ammo carriers, why limit yourself to only 1 cartridge size. With the MAB you can choose how many rounds you want to take with. Are you shooting a Precision Rifle events then 120 is your go to. Annual hunting trip with your 300 Win Mag, no problem either.
Best of all, It will still fit in the original Drag Bag
