Hello, I want to exchange my outer barrel for something around 10 inch so I can have my mock suppressor inside my rail, I'm not sure about compatiblity and I looked around the kwa forum and I did not found exact anwser, only people saying they heard Users try them, I`m looking to buy an Dytac 10.5 Inch night hawk ( black or silver I`m not sure yet) or maybe a madbull DD government steel version
Will any of those fit my kwa lm4?

Also is silver even an option? They do look good alone, but I'm not sure how it will look inside a rail.. anyone got any picture?

here is mine with a TAN outer barrel. it looks kinda silver in the light. I wasn't a huge fan of it so i have since painted it black.

You do know the stock LM4 outer barrel is a 2 piece design that can be converted to around 10" from the original 14.5"?

Well you may need to heat the joint just beyond the gas block/front sight post in order to free up the connection between the outer barrel extension and the outer barrel. Then you can remove the outer barrel extension by spinning it clockwise with a strap wrench, and if all else fails a pipe wrench.

Heat will soften the LockTite enough to remove the "outer barrel, front" (#64).  You do have the manual for this gun, right?  :)  Usually takes a lot of heat, it's not designed to be taken apart.

Using a pipe wrench may break the upper receiver which seems to be made of a dozen parts unlike the monolithic machined forging of the real M4 Carbine.

I did this last night.  I used a simple blow dryer to heat the barrel until it was almost too hot to touch then used channel locks to remove the front part of the barrel.  It was a complete PITA, requiring the torque from the channel locks pretty much until the barrel extension came off.  I also wiped the threads down while they were still hot to try and get all the residual locktite off.  Go slowly to make sure you're not damaging anything you want to keep pretty, and more heat seemed to help (at one point, the locktite started to ooze out of the joint, that's when I started trying to remove the barrel part).  In the end, I think it's a pretty sweet looking, significantly shorter barrel.

One note, I trashed the extension with the channel locks.  I tried wrapping the extension with a rubber grip pad but had very little luck.  If it were mine to do over again, I'd try wrapping the barrel in either duct tape or electrical tape.  It's a whole lot easier to get tape residue off than re-shape and re-black the barrel extension.  If I weren't convinced I'd never leave an sbr type build, I'd be more upset...

Just my $.02.  Good Luck!

Nice, thanks for the information! My problem is the locktite they put on my gun is crazy or old or I DONT KNOW! but removing the delta ring was so freaking hard I had to cut it in the end, I had all the tool to do it too. I tried with a channel lock and hair dryer first, no luck. Then I borrowed a heat gun from a friend and heated the thing until it was impossible to touch, I couldn't even removed it with the AR wrench I had bought and the game to hold it in place. I'll just buy a shorter barrel.. It sound a lot less complicated. Thanks for the information everyone tho! But something is wrong with my locktite lol

Yeah that locktite is insane... I was in your boat and had to cut my delta right off also.. using the armourers wrench and everything... no hope!

Also, when trying to separate the barrel, if you twist it just a bit to tighten it more it can break the locktite and help you unscrew it. I used the hair dryer, and then boiling water and thankfully me and my brother are fairly strong and managed to get it apart with our hands!

Good luck!
