I'm painting this figure right now. Fit is generally excellent except for a huge gap at the back where the torso meets the legs. I filled that with putty.
If one leaves the radio off, one can place five 20-round SCAR mags in the front vest for 100 spare 7.62mm rounds.
I glued my radio on as the photo indicated and have four mags in front and one mag on the MOLLE pouch for 100 spare rounds (+20 on the SCAR-H), or 120 rounds total.
The kit comes with six spare 20-round mags or 120 rounds (140 rounds with the SCAR's magazine), but one can be hard pressed finding room to glue all six spare magazines unless one doesn't glue on the MOLLE pouches.
It's a really nice US Army Special Forces figure sporting the latest US Army equipment.
