    Little embarrassed to say, but I've got a similar issue with an allen headed grip screw that came with a TD Battle Grip. Installed on a Colt lower. I decided I wanted a more substantial grip and tried to remove it. No dice. I guess the Battle Grip isn't so bad after all...

    That sucks man. I'd see what Umbrella will do for ya about it. Must be a new thing as mine came with a baggy with one of each, and said use the red coated one for a permanent install and use the other one to "test it out" or something like that. I just threw the red loctited one in the parts bin. Too easy to mess up a good lower and IMO no need to ever use red on anything. Think I'll inquire to why they don't just use blue. Takes some effort to remove when it's really coated, but not close to red.

    I heated it, cooled it and finally cut the grip off and cut a slot into the screw so I could turn it out.

    I like the slotted screws (nice big slots) that BCM uses as they have a star washer on them or the hex head screws better.

    Sorry to resurrect an old thread, but I had this exact issue last night but I was fortunate enough not to strip the screw. I just put all of my monkey strength behind turning the screw and carefully and slowly backed it out. It literally took me 20 minutes to slowly (mm by mm) back the grip screw out. I was certain that there was something wrong - but the culprit, it seems, was just the red Vibra-Tite (not Loc-Tite) that comes installed on these - A very small dab of Vibra-Tite on a grip screw is a great thing (along with the star washer), but just a tad bit too much and you'll find yourself in this situation. Where Loc-Tite "breaks", Vibra-Tite is gummy and can make screwing and unscrewing quite difficult during the entire swap/install while applied. From now on, I'm going to scrape off any excess threadlocker (if you can see a blob, there's too much, there should just be a fine coating on about 6-8 of the threads or less). Did the OP ever get the problem resolved?

    I forgot to post back while recovering from surgery... I finally took it in to my gunsmith. It took him a couple of days to get it out since the screw head was pretty messed up. He said the same thing...the threadlocker Umb Corp uses. I remember there being about a 1/4" of the stuff on that screw. The color didn't raise any red flags until I got it fully seated...then I began to wonder.

    Cost me $5.00 and the lower threads weren't damaged, so it turned out ok in the end. I have my old Magpul grip back on and will be happy with it.

    Thanks for the clirification on Umb Corps thread locker stuff. I will do the same as you recommended if I ever install another one of their grips.

    No problem - always follow these rules when using Vibra-Tite and you won't have this issue again. If used correctly, I prefer it vastly over blue Loc-Tite and it's reusable to boot. Plus, the ability to pre-apply it to your screws can save a lot of time in the construction process. The only threadlocker I use on my weapons now is red Vibra-Tite on my grip screws, BUIS, scope rings, light mounts, BAD levers, Noveske STS-60 levers, screw-in style handstops, modular rail sections, and A1/A2/Magpul UBR stock screws.

    I hate that stuff having had an issue with it before, I am now a big fan of T Handles a star washer and Allen headed bolts.
    That red stuff is the devils own spooge.

    Put in a good screw and a star washer, charge an extra dollar or whatever it takes.

    Umbrella seems to have since changed this. The most recent Grip 23 I got had some silver looking compound on it and just included that one screw. Different than my FDE grip 23 that had both a red locktited screw and a plain one (with a note about the loctite). My black grip 23 just came with a regular one. I just used the tip of a knife pressed against it, and spun the screw until all of it was removed. From there added my own blue loc tite and issue resolved. I almost never use anything with pre-applied thread locker and just remove it before use.

    Use a soldering iron held against the head of the grip screw head for 15min. If it's got red loc tite maybe 20min.
