OK, so before I boogered this up I thought I would ask the hive mind what to do. I have a YHM free float rail that I put the YHM endcap in with the supplied locktite (don't remember what color it was...blue maybe?) and now my plans have changed a little bit and I want to take it off. What is the best method to get this sucker off preferably without tearing up the rail or the end cap? Should I heat this bitch up a bit with a torch before even trying? Help me before I destroy something!

Hot air dryer first, it's worked for me in the past. Why would you bother with loctite on the endcap? Even if it gets loose, nothing will go wrong with the rifle. Even if it falls off, nothing will go wrong with the rifle. Plus the gas tube will prevent it from moving too far anyway. |

I just finished a pistol build with a YHM carbine length FF on a 7 1/2" barrel. The end cap is past the gas block. I haven't used the blue lockttite yet. ETA see last pic |

You can use the YHM wrench or a similar barrel nut wrench in the holes of the end cap to take it off just like you would use it on their barrel nut. You should have enough grip to remove it without messing anything up especially if you heat it. Of course if it's behind the FSB or gas block you have to remove the GB and the tube first.
If your are taking the rail off, just loosen the anti rotation screws and jam nut then unscrew the entire tube with the cap still on it. The hole in the cap is big enough to go over the FH as long as the GB isn't in the way. |
| If you used the locktite that came with the YHM end cap, the locktite is purple and its about the most mild locktite you can get. You should be able to just wrench it off. Use a hair dryer or heat gun if it is being stubborn. I just put a YHM Light weight Specter w/ the end cap on my new build. |

The open end barrel nut wrench works with the rail on the barrel using two of the three prongs and slightly angled. The YHM wrench works best with the rail off of the barrel, again using two of the three prongs. This way is better than trying to do it with the rail still on the barrel. I took my YHM's off, so the only pictures I can take are without the barrel in the way, but it'll give an idea of how to use it.

| i used the purple locktite that came with my endcap, let it cure 24 hours and it's looser than a $3 whore. i can't tighten it all the way snug or the holes won't align to allow the gas tube to pass through. i added a little red locktite but so long as the gas tube runs through it, i can't really go anywhere. |

I guess I should have mentioned that this is on my dedicated 22 upper with an M4 profile barrel and a specter length rail so no gas block and if there was one it would be past it anyway. I haven't tried it yet but I guess I will just try and wrench it off first and if that doesn't work I'll heat it up.
