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

wow everything looks great.

A couple of questions:

1. why is the cylinder unported considering its a short barreled rifle?
2. What battery size fits the crane stock model? Subc/mini etc etc.
3. How's the gearbox holding up to the canadian winter? :)

I have to disagree, I recently opened up my gearbox to change out the shitty piston head they all come with. To my surprise however, the reinforced gearbox was packing:
- 8mm ball bearing bushings, shimmed to perfection.
- metal ball bearing spring guide
- non-linear m110 spring
- the piston head being replaced had bearings which I used on the replacement as well.
- Piston showed no signs of wear.
- Bevel also had 5 grooves.
- Gears were well lubricated.
- cylinder head has only 1 o ring, made proper seal but also was made of plastic. Looked like something you'd rip out of an JG or echo1.

G&G is really upping their game, the only difference I see between this gearbox and my G&G is the cylinder head. I can't really knock the G&G's piston head down too much because I play all year round and winter's here get cold. Considering this gun has been played every week to every other week for the past year the piston head definitely did it's job. Definitely was surprised to see no wear on the piston.

Overall SRC and KWA both sport better quality products than G&G, but G&G isn't too far behind.

Looks great. Maybe I should pick one of those badboys up :)

BTW, For those who don't know.. The G36 models are almost identical in parts and materials used in the mechbox.

I cracked mine open not too long ago to check it out.

Ever since we started having the SRC Gen III Pros, I have a lot of people asking me to compare Gen III with Gen III Pro. I should really do another review of the Gen III Pro gear box, but here is the differences you will see:

SRC Gen III vs SRC Gen III Pro

Gen III has 6.05 tight bore barrels, Gen III Pro has 6.03 super tight bore barrels
Gen III has M120 Spring, Gen III Pro has M140 Spring
Gen III has Steel reinforced gear set, Gen III Pro has Steel reinforced helical cut gear set
Gen III has regular motor pinion gear, Gen III Pro has Steel CNC motor Pinion gear
Gen III has tinted glass fiber receiver, Gen III Pro has full metal receivers

Gen III Pro is only $ 50 more than Gen III

Ken

Helical gears, eh?

Don't those require much more precise shimming? How's SRCs stock gear shimming?

Did you buy that from 007? The model on the 007 website looks like it has a metal lower receiver but the version in the airsoft section on milsig has a tinted lower receiver. Hmmmmm

Edit* after reading ken's 3 v 3pro comparison I now understand.

read my review on this problem child

Why bring back a year old thread lol...

But now that it's up: Are SRC's a decent (mid range or up) AEG? I know it won't be a TM, but could it survive a few years if treated right? I've only worked with GBBs so far, so I know very little about the electric gun world. Thanks!

Brought it Up
 

It was an AEG that I bought along with 2 others (GBBR) and I was going to do a review on its all 3 performance at the end of the year...this was a problem child from the get go.
