Spartan452 Posted July 22, 2008 Report Share Posted July 22, 2008 http://ebaybanned.com/product_info.php?products_id=1517 hope this hasn't been posted yet, but here is a red cnced reinforced gearbox, is this the haynes copy? Link to post Share on other sites
RedScare Posted July 22, 2008 Report Share Posted July 22, 2008 no, because this gearbox makes the AEG shoot three times faster =p Link to post Share on other sites
transist Posted July 22, 2008 Report Share Posted July 22, 2008 haha, if its CNC then it HAS to be in an awesome color. Well either way I'm kinda bored with the gray mechboxes. Even the JG black ones I think are awesome, even if they are only painted. Link to post Share on other sites
CrazyJ Posted July 22, 2008 Report Share Posted July 22, 2008 I guess its like steak? The redder the better. Link to post Share on other sites
MDK_Marshal Posted July 22, 2008 Report Share Posted July 22, 2008 Oooh, eighty squids. Not bad, not bad at all. It's nice to see that they've gone for the "normal" V2 design, rather than the psuedo-reinforced rubbish - too much material in all the wrong places... And, from what I remember from looking at pics of the haynes, this aint a clone of that. Hell, I'd be rather impressed if the chineese manufacturers knew that existed. This simply looks like they've got a normal V2, given it one or two little tweaks, and CNC'd it. Still, it's likely to be better than an normal cast gearbox, and at that price,. and including those big bearings, who can argue? Yummy. Also, can someone that knows they're Aluminium alloys tell us how good 7075 is meant to be? I've heard it around a lot before, btu I've got a seive-like mind for metals EDIT: Meh, after a quick google, it seems to be a pretty good alloy. To Quote Wiki: "7075 is an aluminium alloy, with zinc as the alloying element. It is strong, with good fatigue strength and average machinability, but is not weldable and has less resistance to corrosion than many other alloys. It's relatively high cost limit it's use to applications where cheaper alloys are not suitable." So at the very least, if it is indeed 7075, then it'll be of relatively decent quality! At the VERY least, it doesn't look like it's just a CNC'd lump of pot metal Link to post Share on other sites

ryn1523 Posted July 22, 2008 Report Share Posted July 22, 2008 7075-T6 is used all the time in the manufacture of real steel pistol, caliber sound suppressors. It is also the alloy used in the Colt M16 series. When it is hard-coat anodized it has great strength and corrosion resistance. Link to post Share on other sites
M4A1lover Posted July 23, 2008 Report Share Posted July 23, 2008 7075-T6 is also called aircraft grade alumminum Link to post Share on other sites
transist Posted July 23, 2008 Report Share Posted July 23, 2008 7075-T6 is also called aircraft grade alumminum Which is pretty meaningless. Aircraft grade aluminum is nothing but a marketing buzzword now. Link to post Share on other sites
