It's already been mentioned before, but the Magpul USA MOE Stock fits. It's a bit tighter than the default stock that comes with the gun.

Make sure to get the milspec version and not the commercial version. Even though the buffer tube is slanted (commonly found in commercial sized tubes), the diameter and length are milspec.

Lots of magppul enthusiasts. Can I get a Madbull Daniel Defense LITE 9" RAS rail test? Lets start throwing some more things in here aside from all the magpul stuff. Maybe a upper/lower receiver swap? Test out maybe some trademarked uppers and lowers see the compatible versions for those? Maybe even add links to websites that sell the items you tested as well. That way others can obtain them if they wish; just a thought!

Probably a noob question, but, to clarify for others who maybe wondering as well. Are ALL Madbull rails the same? Aside from the look and trademarks of them...?

The Madbull Noveske barrel nuts are elongated with many ports in them while the Madbull Daniel Lite RAS barrel nut is much smaller. On my KM4 SR10, I had to use the G&P barrel nut to secure my 7.0 Lite RAS to the upper. With Allizard's post, you may not need to buy the G&P barrel nut to affix the rail to the upper receiver.

Then you have the Madbull DD Omega series that attach to the delta ring and are secured by pins near the receiver. The DD MK.18 rails and the rest I'm not so sure about, but will probably use the same barrel nut as the DD Lite RAS.

I would be very interested.in speaking with that individual who owned the DD 9.5". I mean, if I really had to I would buy the RS, but, those rails cost more then the gun itself did. Anyone experiment with aftermarket upper/lower recievers? I love my Colt™ body, but if I could I'd be interested iin exchanging my LM4 lower and upper with a DD or something.

RS bodies won't work with the LM4. The Madbull rails will work on the LM4, as will the RS DD rails. No other aftermarket upper or lower receivers will work (without modifications) with the LM4. We have to wait until someone makes one for the KWA U.S. version LM4, not the KSC or overseas version or KWA USA releases the uppers to buy separately.

Thanks for the clarification! I was looking at the madbull DD lite rails and was praying they'd work. Worst comes to worst ill add'm to another gun of mine and save some coin and buy the RS rails. Thanks again!

can you go more into detail as to what you heard gets ruined with the npas/nozzle? i want to order one and basically take out the npas and put it in the LM4 nozzle shell. reason for that is because i dont think the ratech nozzle has reinforced metal nozzle tip and bb loader arm(not sure if thats what its called lol) like the LM4 does and i really like how kwa designed the nozzle..has anyone done what i want to do to it yet?

It will come with it's own barrel nut. Allizard posted that a Mabull DD rail for on the LM4 threads perfectly, so I'm betting this will also. Again, you will probably be the test dummy for others to come, but it looks like the rail will work.

Allizard would have the best explanation as he's the one that told me about it. Feel free to try it out, your more likely to ruin the NPAS than any part in the LM4. From what I understood, the NPAS is the part that gets messed up.

I would like to know more about the NPAS issue.  I am also and the verge of ordering the RATech nozzle, only to take the NPAS out and install it in my lm4.  I am curious as to how the NPAS would be damaged.  The valve and spring are metal while the surrounding nozzle is plastic.  My initial thought is that the nozzle would have a greater chance of getting damaged rather than the NPAS.  

Allizard, can you go into a little more detail about RATechs NPAS when installed into a lm4 nozzle.

Thanks.
