Catastrophic Failure of V2 Mechbox

It works. Even with Airsoft Surgeon Stage 6 springs. You get massive air leaks but the gun shoots reliably enough to game.

Rofl, with the losses i'd expect with a gearbox looking like that you could advertise it as an air-cooled gearbox

when i was in england i only saw 3, maybe 4 gearboxes that had cracked (all ver.2) but only one as badly as that, thankfully i've never had it happen to me..

Manufactures and gun-docs can easily remedy the situation by just de-stressing the front of the mechbox by radiusing it (before it breaks of course). Its a basic ME principle to eliminate the stress fracture points.

BTW...most mechboxes that claim to be "reinforced" are reinforced in the wrong places. Marketing BS to make you think your getting a stronger box when in fact your not.

^Ya they seem to be reinforced in the back mostly. Which is pointless cause they break on the front lol. As far as V2 goes I run a cheap mechbox so if it breaks its cheap to fix. I am running one of those black JG ver2 boxes. They are great for $60 and of they break it only cost $60 to replace.

Well it doesnt matter what you do to the mechbox if it's a marui. The only way to prevent those from breaking above 330fps is with the ARS sorbo cyl head, or adding a sorbo tablet to your current cyl head.
Beyond that, you need a better metal, G&P makes mechboxes that are tough as nails, they've got some of the best low quality metal that airsoft guns can be made out of, that's why we all LOVE their M4's lol

I'll second that. I had 2 TM mechbox shells snap off like that - one at 360 FPS, and one at a mere 340 FPS. It's quite normal as the original V2 design was intended to be fired at sub-300 fps velocities.

Reinforced mechboxes ftw. Not expensive and will save you a lot in the long run.

It seems like even G&P gearboxes are not immune to cracking either: YouTube- G&P m4 special forces problems

[DarkAngel]

No V2 box is immune to cracking. I dont care what people say.
Ive seen every brand out there break in one way shape or form.

300fps and Sorbo pads make it immune lol
