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.

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 the same barrel design and the latest batch of KM4 RIS is now using a 1 solid piece outer barrel. However, the tip is still glued on and must be heated up before attempting to remove the flash hider.

SERVICE ADVISORY - MP7 Bolt Catch fails to lock
Posted by KWA [Jim R.] on 25 February 2010 11:03 AM

We have received a couple reports on MP7 Bolt Catch fail to lock when magazine is empty.

The problem is due to damaging the BB Follower by continuously slamming/springing the BB Follower when magazine is empty.

MP7 Magazine

This should be the correct position for BB Follower when BB is emptied in the magazine.

When BB Follower is pushed all the way up, it will engage the lock to catch the bolt.

When BB Follower is damaged. It will caught outside of the mag well and will not push all the way up.

Hence the Bolt Catch arm will not engage and fail to catch the bolt when mag is empty.

Do not release magazine follower when the magazine is empty. Doing so will damage the magazine and magazine

Recently, we have been getting in a lot of returns with a cracked hopup. 

After inspection, the common cause is related to installing after an market flash hider. Many of them have a smaller inner diameter and cause the barrel to push backward into the hopup unit.  

See video below.
