This beauty right here

The part about site fills was just whether you’d need convincing to go to a 13ci from a 48ci, or if you didn’t have site fills and needed extra air etc
 
I can’t think back for certain - but a MOLLE MP5 pouch should fit a 13ci, and would fit one column of MOLLE.  I’ve used them for paintball pods, which is tight at first, and I’m sure I’ve put my 13ci in one before.
(I prefer to lose the remote line and use the bottle on the gun to avoid tangling etc)

There’s also the option to make a skeleton strap bottle holder for a 13ci.
Two or three horizontal strap loops and one vertical strap to secure it
 

i use the back pouch on the smersh, it's literally the perfect thing for it.
 
however i've seen folk gut hydration bladder backpacks and run their tanks in them, might work a bit better for your setup.

Thanks to rocket aka John and his images myself and someone skilled in fabrication, converted the armorer works drum mag.
 
Tested this weekend in game rather than proper testing the gas amount came close to the amount of bbs and it left a great smile against hpas and aegs alike.
 
So many are interested in the MWS when they hear it and well they should be. Still semi auto is the only way to use this for perfection
 
Now just to tidy up the drum and paint

Touchdown! It's here. Awesome! Now the fun begins!
 
(Actually it's ice cold so I'll let it get to room temp first. I'll have to look in awe for an hour or so....)

Play style is everything with these. I probably don’t go through 600BB’s at Anzio over 8 hours. However... I’d say my hit rate % is much higher for what I carry. 
 
If I see someone at distance, I decide if I think I can hit them, and take a couple of shots. If I can’t hit them in 3-4 shots then there’s no point firing anymore, so I reposition or just move on. 
 
Its much more satisfying getting a kill with a GBBR. 

Leave it a week or so and Fire Support will be getting some in - 72 if I recall correctly.  Alternatively, Daves Custom Airsoft had a few left
