Bulle mag pouches can take G3 mags, can't remember if they come in black.
And iirc the king arms molle DOA pouches took G3 mags too, though a bit tight (ooherr)
FELDJAGER is dead on, that will work. However neither my CA or TM selector work properly with it, so i just stuck the CA one on without the selector bearing that locks it, so now it slips out of semi all the time, no worries though as i only use full auto on my SG1s
Aye aye, he has a point Most do stay working to be fair, but when it comes to G3s they get modded pretty much as soon as i get them.
Thats my 3rd SG1 too btw
*fap fap fap*
Why would you need to upgrade it though, in stock form its fine...
And i don't think TM ever make guns with the intention of them being upgradable, afterall they don't make any upgrades themselves do they?
