Due to recent enforcement of US importation regulations of airsoft replicas, orange tipped flash hiders must be permanently affixed onto the barrels to help law enforcement distinguish an airsoft gun from a real firearm. Altering or removing the coloration or markings required by state or federal law is dangerous and may be a crime. The user assumes all risks and responsibility when doing so.  *** This also VOID your warranty ***

If removal of the orange tipped flash hider is necessary for service or repair, please follow the directions below.

The barrels of the KM4A1 Carbine, KM4 CQB, KM4 RIS have a two piece construction. Improper use of force while removing the flash hider may result in barrel breakage at the threads. Please use a heat gun, preset at 350°F or higher, to soften the adhesive inside the threading on the flash hider.

DO NOT
attempt to remove the tip while holding onto the body of the airsoft gun as shown.

Use two vice grip or channel lock to hold the gun at the two indicated areas. Secure A with vice grip while twisting B counterclockwise to remove the tip.  Note: To avoid damage to the barrel surface from the vice grip, warp small strips of cloth around barrel area A and B first.

FYI... not ALL models are affected. SR series do not have same barrel design and the latest batch of KM4 RIS is now using 1 solid piece outer barrel.  However, the tip is still glue on and must heat up before attempt to remove the flash hider.

on my sr-10 I didn't heat the flashhider, i just stuck a screwdriver in the space in the flashhider and used a bit of elbow grease and the glue broke right off... it's probably easier if you heat it tho.

remember our factory just started to implement this beginning this year.  Your SR would be before Dec 09 so it might not be glued.

Haven't tried this on a KWA, but it has worked well on others:  Fill a coffee mug with boiling water, then immerse the flash hider for about 90 seconds.  This seems to loosen the glue as well (especially if you don't have a heat gun handy).

Is the theard between the two pieces of barrel counterclockwise or clockwise? And is it also glued?

What I do to get all my flash hidders off my guns is take a sodering iron and remove the inner barrel and hop up unit and just put the sodering iron down the front of the flash hidder and wait and it gets hot really quick and you really do need like oven mits to protect yourself cause it gets a little hot lol.  It works quite nicly.  I've done this to my friend's Kwa KM4 and it worked in about 5 minutes.

Same here. I removed flash hider from my M16BR purchased in May 2010 with no heating, just screwdriver and force. There was something on threads, but I didn't know it was glue at the moment :) I was lucky I guess that I didn't twist anything :) Next time I'll use heat.

I'll ask again - I want to transform my M4 into M4CQB. So in what direction should I turn the second part of the barrel? I don't want to damage it...

Good Evening,
I just wanted to double check that these instructions are still correct. I have recently purchased an SR-7 and wanted to add a Noveske to the front.
Thanks
Eric

Not sure I understand the question.  Noveske..what?  The barrel instructions are for the later model M4A1 and CQB model KWAs.  :gun:

i also use a heater whenever i mount or dismount my barrels, for cleaning and maintenance purposes. although, lathering in a glue or teflon tape wouldn't hurt. it also helps when the barrel heats up, i tends to soften and grips more into the joints and when it cools down it gets harder. so always use a heater before twisting it off.

How long does it take for the glue to heat up? I heat it up using 500degree preset and it still wont twist off. Not using vice grips but I am using a pipe wrench / wrench combo. The barrel is extremely hot when I try to take it off so I feel like I am doing it long enough but am curious as to how long you recommend?
