SACair Forum

Hi all. Has anyone heard of mechboxes machined out of solid aluminum? I want my TM G3 SG1 to shoot 550fps (w/ .20 BB) but i dont think that is possible with a typical cast metal mechbox. Any ideas? Dont be too cruel, I am new to the Sacairsoft forum :lol:

nvm, dont want to give a metallurgy lesson.

PGC?

xyz?

msg?

mgs?

WTF?

c172200 beryllium-copper

yes?

YES!

you guys are funny. :D

aluminum is good enough, especially for the price of what we usually want to pay.

what about a titanium one?

okay here are numbers. tensile strength in MPa, mega pascals.

eh....smartass... :lol:

[quote="paintballbum2006"]PGC?[/quote]PGC.....These gear boxes are the only ones on the Earth made from Billet Aluminum 6061 T6. wurd Stan! **Edit** Oh and the PGC GB is only made for TOP M249's.

wow 6061 T6 is strong stuff --- 310MPa on the easy side.

Wow, those numbers are cool sounding, but what do they mean? What tensile i would need?

lol

so what you are saying is those Rice Rocket freaks are incorrect....

Solid machined aluminum gearbox? unobtanium.

so...are those values for tensile strength or ductile strength?

I use 6160 in my training knives. It's a pain to work with, even using a grinder and cutting disk.

So it sounds like no one has ever seen a mechbox that was milled out of solid aluminum.

SOlid aluminum gearbox wouldnt crack I dont believe...

hey someone try the highest systema spring and a 12v battery and lets see what happens... im really really curious.

Maybe the guys at Airsoft Extreme would like to do a test? :mrgreen:
