Hey, guys. I'd like to do the rocket valve mod on my LM4; however, I'm having trouble getting the C-Clip off of the BCG that holds the nozzle in place.

Does anyone have any tips on how to get it off without bending the clip itself? I tried to use a pick and even some snap-ring pliers but couldn't get any leverage on it.

Thanks.

Use two small screwdrivers; one at each tip of the open end, and apply pressure up. Put a finger above the e-clip when you do this, otherwise that little thing will rocket across the room. I actually hold one of the screwdrivers in my mouth so I can hold the bcg in place and apply pressure to the other screwdriver with my right hand.

Heh, yeah it's kind of a three handed operation. I haven't tried this myself, but perhaps putting the BCG in a plastic bag, then doing the same method through the opening of the bag, would prevent the clip from flying into the abyss?

Good luck PonZee!

It's actually super easy! Some people advocate spinning it around so that if it were to come off on its own(which is nearly impossible) then it would run into the raised part of the bolt and stay in the correct spot.

The two little screw driver method works for me and it gets easier with practice.

Even the KWA techs have trouble with this.  :)  My LM4 came back from warranty service many months ago with the rear of the bolt carrier all scratched up in that area from removing the C-clip.

Something you may want to try, I modified a pick tool so that I can easily pull off the clip in a second and with one hand. I also grinded the other side to have a flat edge to push thr clip back on easily.

Exactly.  I do this and use a small rear earth magnet in the end of a rod to catch the little sucker as it tries to fly across the room.
