The actual G36 burst irl is 2 rounds, so it being 2 round is fine either way.
well HK offers it in a bunch of configurations, from 2-3 burst to just semi-fullauto. IIRC the German army version has no burst.
the latest hotfix may have broken the tiered fleamarket setting, i have it enabled yet i can buy everything off the flea at lvl 17, could not do it on last hotfix.
Oh dear god I hope you're wrong
