[Brian McIlmoyle]

if you are playing short sharp engagements with little expectation of having to sustain yourself in a fight for a long time you can probably get away with a solid first line rig.

3-4 mags , a holster and a couple of mags for you secondary, plus a couple of utility pouches for other bits .. and you are golden.

Then later on add a chest rig for sustaining a longer fight.. longer games

Then later on add a assault pack for longer term sustainment

then add a large pack for carryign your gear for a 24 hour or longer game.
