YOU TUBE: SRC GEN III Gearbox Review
 

YouTube- 007 Airsoft - SRC Gen III M4 Gearbox Review

Edit: Shimming was done properly, in fact, exactly how I would have done them. Without the cylinder and spring assembly, the gears can spin freely even with a tightly closed gear box. There is only very minor play for the each gear axle between the corresponding bearings.

Edit: Back side of cylinder head is lined with a rubber pad to absorb impact from piston head :)

Ken

thats a great review!

only thing i think you forgot is the shim job...

hmmm i think aluminium piston head is not ideal in here... adds a little bit of stress on the shell... other than that it looks like a very good mechbox! the airseal seems very good

i would change it for a sorbo pad head. Please review the g36's !!

Agree'd!

Mmmmm 100% air seal.....

Bought the SRC HK416 and it hasn't disappointed me yet :)

Do a review! =P

EDIT: Wow that lower is tinted.

Cansoft isn't looking too shabby anymore.

Looking real good Ken.

Cheers.

no upgrades needed there!

It looks like they've lubricated things with oily lubricants instead of waxy/tacky lubricants...

But that may have just been the video, it was difficult to tell.

These things look like they're miles ahead of any G&G CANSOFT I've seen lol

lookin good.

Ah that grease looks good!

The only downside I can see is that they cylinder head isn't Sorbo compatible.

You can always get a modify cylinder head. But that cyclinder head is good to perform with that aluminum piston head. Sweet.

Too bad the hk416 isn't the right lower. lol
