| I'm having a couple of problems disassembling my kit. No matter how hard I pound on it, I can't get the locking shoulder to budge. I also can't get the gas tube nut to unscrew. I've tried an old style can opener and putting a screwdriver in one of the slots and hitting it with a hammer. I can't get it to move either. Is it reverse threaded? Would they have used locktite, solder or something? Any help would be appreciated. |

This may be my problem with the LS. I didn't realize this other piece is supposed to come out of the receiver stub as well. I think it is the magazine release lever. How does it come out? I've taken out the pin that goes through it, but I can't get it to budge no matter which angle I hit it from. Sorry for the bad pic, I borrowed it from another website:

Guess that's not the piece, I found the mag release lever in my bag of parts. I'm about ready to scrap the LS and just buy a new one when I headspace my receiver. The piece I'm looking at sits under the LS and rides along the bottom of the bolt. It had a pin that went through it and the receiver, took the pin out, looks like it should come out but it doesn't. Does the housing that the bolt hold open and mag release lever sit in come out of the receiver? |

I had one locking shoulder I had to use a air hammer on to get it out. Make sure you knock it out from the correct side, (I know that sounds stupid, but you never know). I ground a specal wrench to remove the gas cylinder. I think the bottle opener from a SWISS ARMY knife may work. Maybe you can heat it up a little. (the gas cylinder) Be careful not to melt the carry handle. Let us know how it goes. Court .223 |
| I have always found that a hydraulic press is the best to remove and install locking shoulders. A good product to use with it is the Aerokroil penetrating oil. Spray it on and let sit for about 15 miutes. I have never had a LS not come out with this method. Take your time and try not to destroy anything! |
| What do you put in the press to press against the LS? I kind of tried this yesterday with a vice, but couldn't find anything short enough. I bent every nail and screw I tried to use. I've already bent one punch trying to get this thing out, I don't want to ruin anymore. |

I finally got the damn LS out. I ended up drilling a hole in a piece of wood to use as a backer, and then used the vice and a bolt as suggested. Took quite a bit of pressure but it finally popped. There was a gold "film" in the channel for the LS, couldn't even scrape it off. From which sides do you measuer the LS? I either get .266 or .259, depending on which flat side I measure from. |

Look at how it sits in the receiver. The measurement you need for headspacing is the front to back dimension. The front facing flat is usually not milled/ground as wide as the top flat is... Remember how the bolt locks up. The ledge on the lower back of the bolt drops down (is forced down by camming surfaces in the bolt carrier) in front of the locking shoulder. |
