I heard that WE magazine leaked alot.

After having a KJW for so long:

+ Never had leaked magazines even after I took it apart and assembled it again
+ Bolt cycle always full and crisp until magazines empty
+ Very very very durable
+ No problems whatsoever since the first time I got it
+ Very minor upgrade for better accuracy and increased durability
+ Very loud sound when firing (this is just great)

- Recoil not as strong as other brand (but the ver.2 bolt have harder recoil so its not an issue).

Compared to other brands that I heard and read about, I think this is a hassle free, ready to use and a rock solid GBBR to date.

EDIT:
Guys using this free float rail, do I need to use the gas tube? Because the gas tube wouldnt fit. Thanks.

No you can remove it. The gas tube doesn't do anything, it is just for aesthetics.

I had that same style RAS, mine was made by G&P though... The Gas tube stops the delta ring from moving and locks it in place.

Does yours comes with the gas tube? Or did you use the KJW m4 ones? My kjw gas tube cant fit in my RAS.

[Saberwing]

Mine fit perfectly fine. What brand is your RAS? I would take pictures for you, but I've since sold it and am now using a Daniel Defense RISII 9.5"

Its RAMBO, ACM RAS. Should have go for the G&P instead.

Sorry, is the V2 Bolt an optional upgrade? Or are the KJW ARs now shipping with the V2 bolt from the factory? Is there a way to tell the difference from the packaging at all?

AFAIK, the M4s will ship with the V2 bolt. Not sure if they still sell the V1 bolt separately though.

You could ask the retailer to open it and check.

[Amos]

It'll say "Verison 2" on the packaging

I think my mag might leak a little bit, not sure whats the cause, but I can hear sounds from the top part of the mag (the one which gas comes out) It sounds like when theres problem with your telephone, like a pricking sound. Anybody know where the problem might be?

I have had one of my mags do that, it's probably coming from the knocker valve assembly. Try adding some oil to it.

Anyone figure out how to disassemble the V2 bolt yet?

[Cj Radge]

Hi LocoYoko, its easy to disassemble the V2 bolt. I'll try to take pictures on step by Step.
