Yay, it works and i got it Algobox-ready.
-Semi-Auto only
-Bolt and Bolt Carrier Group
-Shoots .50 HG (HoverGuy

)
-Direct Gas Impingement Operation (uses scripting :])
-I kinda got the shape
Have Fun! 3 Mags, 1 round already chambered,
mag release below the trigger guard, Return to fire(semi).
If the bolt doesnt close and lock properly and you can see
a yellow spring on the bolt's end, you just broke the extractor.
Thanks 4 that. Please note that this thing is just a proof of concept,
and has a weak ejector (I suck at building non-scripted ones

)
Excuse: Game-Balance.
