KJW M4

Recommended Posts

I figured that would be the problem. With gas efficiency issues normally the problem is one of three things:

 

1. Mag valve sticky

2. piston seal issues

3. flute valve issues

 

Glad you got it working.

So it seems what is recommended is using propane for operation. Should I fill the mags with Green Gas for week to week storage in order to keep the mag seals from drying out?

No, I don't even know if anyone has had issues with seals drying out yet. The valves need to be manually lubed every 5,000 rounds but that is done in a different way. Just leave em!

i think i know what happened. most gas gun boards consist of talk of problems and issues with guns. we don't have that here at kjw, so members start turning on each other over lil things that don't really matter.

Had a major failure today. The tabs on my upper receiver broke off from normal shooting, now my gun won't stay closed. Anyways, I am about to start my new career, so airsofting may not be in my future. I plan to sell everything KJW GBBR related and just buy an aeg to have when I need it. If you want anything let me know. Will post my for sale thread soon.

The tabs shouldn't break from regular shooting alone. They were likely weakened from opening/closing the receiver and then finally gave way during use. It is a flaw in the design though. Rumor has it that KJW is fixing this issue in future releases.

Did you use a single point sling when you ran the gun in skirmishes?

Hopefully one that they CAN ship to the US

 

As far as I know, KJW is not interested in shipping any metal uppers or lowers to the United States, Period.

 

They might change this if a few thousand people requested them, but they refuse to send dealers these parts.

I don't see why they don't considering an upper isn't even considered as a firearm

 

The general consensus has been that they just want to avoid the ATF and other countries regulatory agencies all together.

 

When the ATF starts poking their noses, your company will have some serious issues importing stuff down the road. Lesson learned with AONW.

 

Ask them, chances are they will not give you a direct answer. I know they didn't give one to myself and several other members.

Off topic, but I was wondering if anyone picked up on the new "cheap" M4 GBBR on the market:

 

$195 WELL M4 GBBR at Airsplat:

 

http://www.airsplat.com/Items/GR-WELL-G16A2.htm

 

Comes w/ a 50 round magazine. So what rebrand is this: AGM? or JG? Or is this some new cheap GBBR?

 

I would not have asked here, except that the receiver resembled the KJW... obviously the magazine is a dead give away that this is not a KJW clone.

Being metal it wont be the JG I expect it'll be the ACM from last year. So a cheap WA system and lets face it even the expensive brand WA system guns don't function that well out the box.
