With my L85 and Brit kit, I'll have 14x 30 round Emags, 4 pistol mags, a BFG, some blanks and the resetting tool for the BFG as well as 3 litres of water and a radio, PTT and headset. That's enough ammo to last me between 1 and 5 hours depending on the game type, ranges, number of people per team etc etc. I've not done any serious milsim games or anything yet, but I suspect if I did and I needed to carry anything else in addition to all that, which weight-wise sounds a lot less than it is, I'd probably end up killing myself, because the rig is a good 6kg with nothing in it. I gain about 4 stone with all the Brit kit on... I don't even run it with plates. Fuck knows how our guys overseas manage to walk around in 40° heat all day every day with it all on, my hat's off to them, they ought to be called Terminators or something, 'cos it must take bionic limbs to be able to keep that up for 6 months at a time...
Anyway though, I figure if I ever need tools, then attempting to fix anything in the field is inevitably going to end in something important getting lost, so I leave tools behind on purpose. I don't take batteries out either, because they take too long to change.
But frankly, I'm far too unfit for carrying all that around to be an enjoyable experience, especially considering the L85 is slowing dying on me, trigger response is so bad compared to the AK that it makes me cringe, and it's got high speed gears, high torque motor and only an M100 fitted, so god knows why it's so bad... So I've shelved that set up for the time being. I'll probably break it out once I'm slightly less cholesterol induced, or the AK breaks lol.
With the AK I only run my belt rig, which carries all the same things in all the same pouches minus the radio which I go without, the only thing that changes is that I put all my AK mags (5 mids) in the utility pouch that I use for "back up" L85 mags.
When using the L85 I'll have 6 mags on my rig in a fast grab location, another 6 on my belt rig in the utility pouch, one in the gun and one in a medic pouch, because there's nothing else in there, and there's no space for it anywhere else lol.
So the AK mags just go in the same utility pouch. It's a bit annoying, because they take forever to get out of the pouch because they're all just stacked in there and they're not held separate, nor can the pouch be left open or they'd all fly out. So it takes ages to reload the AK, but it's balanced out by having my sidearm, and the mid caps being loaded to their full capacity, whereas I'm more used to reloading after 30 shots, which is approx 2 seconds of full auto.
Definitely more in favour of high speed low drag set ups at the moment. Seriously considering getting a gas L85 to solve the trigger response issue as well... But money.
I hate money =[
