    I mount and dissasemble a lot of scope mounts, rings and baases on hunting and varmint rifles. Many on used guns are buggered up as well as occasionally loc-tite'd.

    I have to say that soaking the screws with KROIL for a few days really seems to help. Every time I'm in the shop give them another drop from a needle oiler.

    Also agree with tapping in the next slightly larger hex key. Thats worked for me.

    Good luck.

    Grabits are the best screw extractor I have used to remove stuck allen screws. The other thing I have done is simply drill off the head, remove the lever, and then get the screw out with vice grips.

    I hate extractors. Then again I'd use them on rusty cars (thanks MN).

    Another idea you could try - use a dremel with a cut off wheel. Make a slice in the screw head and use a flat head to spin it off.

    I'd probably just do it the longest way especially since you used locktite. Drill the screw head off and pull the safety out. Throw just the safety in a vice and drill. May have to heli-coil or tap new threads after.

    As someone else said some penetrating oil might help. PB Blaster does a good job.

    These are great^ I have this issue at work a lot and I always use a tight fitting Torx bit to remove them. I don't have to deal with Loctite though, so YMMV.

    Would the #1 Grabit be the one to use for the screw on the OP's ambi selector? I have a similar issue with a BCM ambi selector that I have on one of my Noveske N4 lowers.

    Before doing anything else, take the correct size Allen key and grind the end back so it's flat, then tap it into the screw head and try to remove it. Grinding the end flat will give it more bite. If that doesn't work, then try the other options as outlined in earlier posts.

    Grabbits work well but get dull fast. Don't try to make a dull Grabbit work.

    When drilling the screw, go slow and use some kind of cutting oil. Be prepared to replace the safety. Just get a replacement, don't try to save the old one and save yourself the aggravation
