Tanio Koba / KJW M4 GBBR Basic Information and FAQ

[chris62]

For the purposes of Airsoft almost all guns use the same 6mm bb; so calibre will not matter.

[FridayNightGamer]

The receiver is a different shape to accommodate the larger rounds. The closest things that can be made with the KJW M4 are the Mk 12, SAM-R and SDM-R.

Out of the ASC combined knowledge, can we find what one would need to more or less make a kjw m4 into an SR-25?

Literally not possible. The only parts the same on an SR25 and an AR15 are the ones that aren't unique: stock, grip, front kit (well, not really, but in airsoft, yeah. Difference is barrel bore on the RS. For airsoft, they are the same kits), and accessories. Both the receiver, bolt and magazine are all entirely different. "Converting" an AR15 into an SR25 is not possible.

Wait, I must be missing something. For airsoft, i thought SR-25's were pretty much just an M4 body, with 12" front RIS, and a M16 fixed stock, guess not.

I'm just looking to put a 12" RIS, and fixed stock on. Wondered if people knew what fit. Kody says the front is real steal threaded. As for the fixed stock, no one seems to know. I may try a real steal fixed, or a WA with slight modding to attach it.

What is the threading on the buffer tubes of KJWs? If its real steel threading, than either a real steel or WA stock will work on it.

As far as SR25s go... No sir. In airsoft, there are actual SR25s. I had one. They are gorgeous; definitely not just an M4 body with a big RIS and fixed stock.

Look up pics of the G&P SR25, or the CA25, or G&G GR25. Cool stuff. What you want to make is like a SAM-R, or standard DMR

[andrew321]

Thanks, I'll remember that.

The rear buffer tube is 100% unique to the gun, and wont fit without some modification. That much seems confirmed.


What I want to know (i've heard both) is whether the front threads for mounting an RIS are AEG compatable like

or Real Steel, like a Daniel Defence or madbull.

[baker_Jeff]

The front is threaded for real steel/DD.

[andrew321]

Thank you.


I just need to find one now.

Tokyo Model has an adapter for adding a fixed buttstock. At least that what it looks like its for

[andrew321]

whaaat, that does look like what it would be for...I just can figure out where tf thats supposed to thread into. does it replace the buffer tube? or screw into the end of it??

I'm willing to try it. I wonder if it will fit a GBBR, real steel, or AEG fixed...

[Rookie Ab]

They also have the inner barrel you might want;

[andrew321]

Would an "AR-15 Variant" Real Steel RAS have the same threads as any RS M-series?

http://cgi.ebay.ca/TACTICAL-Free-flo...item4cedaa58aa

I'm picking one of these up if it'll fit

[Goldman]

That looks like a knock off larue 13.2, which can be had cheaper at ebaybanned.com

[andrew321]

Yeah, but are they Real Steel? the whole point of not buying a cheap knock off, is because it has to thread properly.

EDIT: nevermind..it say's "he fits them on ICS/CA/TM AND Real Steel firearms"

[Conker]

The one you linked IS a knock-off. It's written on the eBay page.
