So I have a CQR mod2 and I wish to extend the barrel. I have my eye on a madbull 6.01 inner barrel and a lonex enchanced steel inner barrel. I can not decide which inner barrel to buy. I also don't know which type of bucking to buy for it. can i just use the same bucking that kwa has?

A longer barrel just for looks is counterproductive as far as expense and time is concerned.  Fake suppressor, etc.  But if you want more range and accuracy it may be the way to go.  How much money do you want to put into a $175 gun?

Lengthening the inner barrel requires increasing the air supply as well as putting something on the outer barrel to cover it like the KM4 barrel extension or a fake suppressor.  The air supply requires a different cylinder and that requires opening the gearbox something I've yet to work up the nerve to do!  :)

The Pro Shop KM-Head 6.02mm ID 395mm long inner barrel slid right into my RM4 but that gun had the M4-length barrel and proper air cylinder to start with.  Used the KWA bucking and hopup unit.  Muzzle velocity is up 40fps with 0.28g BBs.  Accuracy testing this barrel remains to be done.

You can use any inner barrel up to 509 mm with out changing the cylinder... You will need a barrel extension or suppressor to protect the new inner barrel... Also the stock KWA bucking is very good IMO...

I use the KM head barrel but not in the MOD2. you can find other barrels that fit the MOD2

KWA bucking was the best choice for me, i use a raptors 6.02 barrel (great barrel $28) & tried numerous cylinders, pistons, pistons heads & springs.

Its for CQB 350FPS limit I had the gun shoot from 398FPS- 422FPS

Ended up using a G&G cylinder, SHS ported piston & SHS POM head & a ORGS M105 spring, shoots 340FPS


Used the top piston & head

Barrel comes with little O ring :) Great barrel

MOD2 stock cylinder on left. huge port, doesn't hold a lot of air like the SHS cylinder on the right, Doubt it will work well with a 509MM barrel

My apologies about the 509 mm barrel. I did not realize the mod 2 had a different cylinder... I have never worked on one... Most people I know hate KWA's with their proprietary parts... And I'l admit that I'm not always a big fan as well, because I had issues with my motor in my SR10 and had to return it the first time I used it even tho I knew it was the motor they made me ship the whole gun (didn't have it for a month)... Also I had issues with my G36C over cycling with 11.1 Lipo... Which took me awhile to figure out because KWA teck department would not tell me the fix... But hands down still the best out of the box gun and the most beefy gearbox I've ever seen!!!

Yea, i was into competition RC racing. And the few cars that had proprietary parts didn't last long.
But, KWA is well made, they have there issues, I don't talk about there motor as i don't think KWA intended anyone to use it too long, mostly to check the gun. JMO

The MOD2 is the same V2 gearbox they just changed the cylinder.
They do make a great gearbox. Im rebuilding a super shooter "CNCed" gearbox, it nice, but i doubt it has the same tolerance as KWA.
So I'm going to use super shooter parts for the build, Im waiting on the SHS trigger switch assembly.

Tales, you know I love ya' man but KWA motors, while not build as well as some after market motors, have served me well in a number of guns well past the 100K round mark.  And I know others who have out them well past 200K.

Sorry, My point is the quality of the gun requires a higher priced motor, and that should be your choice.
I rather choose the motor then pay for something i didn't need for that build. A $40 upgrade makes the gun so much better.

The motor price could be endless! KWA could tack on $75
I posted in a PM or on the board "KWA motors still amaze me" Didn't mean to trash them, All stock motors are stock motors.

It's all good, and I know you weren't trashing them.  In fact, I agree with you.  We both know that there are motors that will take your KWA to a new level and that while KWA motors get the job done just fine there is room for improvement which is relegated to the aftermarket.  In fact, while I still use KWA motors, I have a very nice Lonex A1 in one gun with an SHS HS in another.  It's all about what one wants to accomplish and not everyone can afford to dump another $65-100 into a weekend hobby.

However, I take encumbrance at the misinformed and incorrect notion that KWAs are proprietary to the point of not being able to accept after market parts.  Tales, thank you showing, in multiple posts, that that is not the case and my hope is that people will catch on to the fact that:
  • Swapping an OEM KWA part for an aftermarket part isn't necessarily an upgrade

  • There are plenty of aftermarket parts that will fit in KWAs

  • Not all aftermarket parts are cross compatible....compare an Azimuth half steel to an Azimuth full steel rack piston.  The length is not the same requiring a potential change in AOE regardless of gun

  • Open a G&G or VFC and show me that all aftermarket parts are compatible...TM standard or otherwise.  They aren't.
OK, I'm done....back to inner barrels.

There is no way i can put a SHS motor & a 11.1V lipo in my stock G&G guns and expect them to last two weekends of play without modding them. Sorry, it slipped my mind about the about the cash for a weekend hobby :blush:

Sorry, the thread went OT.

Again no worries.  I indulged myself in a bit of OT posting!

It wasn't installed by me. Its Speaker wire.

I rewired the gear box using Castle Creations 16AWG http://www.hobbylinc...CFW9nOgodnEUAaQ

Tales - Are you planning on using the super shooter gearbox in a KWA lower?  I've read many times that non-KWA gearboxes don't fit in KWA lowers & would like to know if you made it fit.
