KJW M4

Recommended Posts

 

I doubt it. Probably a stock V2 bolt with the velocity reducer or something in it. If not they probably just got it wrong. Although it the bolt was designed by RA-Tech I can see why its failing so much...

 

I still think it was a really bad call for KJW to change the bolt and magazine contents. At least cradle will have a nice bolt up soon. Even if the bolt was 80usd I would buy one if I got a V2 KJW M4 (I am not trying to jinx everyone haha)

Looking good, but haent test it yet in the field. Took me days to find someone willing to do it, as I dont have the required tools. Hope its worth it, Thanks to weekeny for the help on the tutorial :D Very much appreciated.

Saw the tutorial on here the other day (sorry I forgot who posted it but thank you so much!) Turns out finding a washer ring is very hard in my country, still didnt get one, so I swaped it with a teflon ring painted black. Took it from my couch's legs and cut it, so far looking good although its far thicker than a washer ring, I still would like to find a washer ring though.

Looks good happy I could help.

 

Should work well. I use some PTFE thread tape on mine to make sure it doesn't work loose. Prevously I used a small amout of locktite but the tape works just as well and no risk of using too much and seizing the screw. I've also now got proper grub screw rather than a cut down one. The grub screws are described as "dog point" this means that the last few mm are not threaded (slightly narrowed dia). There ideal if you can source them.

Ah I think I have that tape lying around somewhere. How many layers did you wrap it around the screw?

If anyone has a cheap or broken M4 they want to get rid of I'm looking for a new upper to do a mk18 10.5 inch conversion on, and to also play around with the hop-up a bit and see if I can't get some form of R-hop functional in it. PM me if you do!

Um 2 or 3 just go by feel as it will depend on the tollerance between the screw and the cut in thread.

 

Got it thanks, will post the results after I test the TDC mod and the tape. Currently seeking for the grub screws you mention as it might be safer to use it with the tape. Mine is still the cut down one, wouldnt want to break it if I wrap around with the tape too much. Anybody know where I can get the washer ring mentioned in the Magpul ASAP videos? Try to go to a car parts store but couldnt find it, motorcycle as well.

Has anyone looked into shaving down the lower ridges on the magazine body? I'm looking to use shorty KYWI pouches for mine but I both am not sure if they'll fit with the thermold ridges and I hate how they look. On first inspection the mag body doesn't seem to need them to maintain its integrity.

Dnt know about the ridges but I run mine in Esstac kywi pouches, full size and short, and they fit and hold fine. The full size ones are a bit tight but just means they are even more secure.

Glad my tutorial helped you =) Nice work on the teflon ring. Even here in my area, that washer is hard to find, I just found mine lying around the house. For those who cannot find a washer, they can just sand down the inner buffer tube, 1mm is good enough ;).

Thumbs up for you Cj, I didnt think about sanding it down, might try it later on :D

Hello friends, I'm thinking in buying a UBR stock for my rifle and I don't know if it fits the buffer tube of the KJW....Anyone knows if it's possible?...I know there's two types of it, AEG and GBBR but, the GBBR i've found, always are for WA...and that's my point of doubt...any help would be really appreciated!...thanks!

I believe there is discussion somewhere in this thread of using the AEG version due to the internal tube in the buffertube, do a search and you may find more info.

That looks fantastic! What length inner barrel are you running in there and how does she shoot?

@ Shabby. the inner barrel is modified AEG Prometheus 6.03mm diameter/ 510mm lenght barrel. I am yet to test it hehehe, There are many things to consider to make this a performer sniper rifle... from the quality of inner barrel mod to increasing the power source to compensate the lenght of the barrel. It can be done by either using more powerful gas or stronger hammer spring. Hope this performs well, if all efforts are exhuasted and does not perform the way I want it, this project will be scratched. Let's see. =)
