Stuck screw in red dot mount need advice and help

[Gindryden]

Ok so I got my red dot mounted on the Glock. Used blue loctite on the screws but took it out to the range and it came loose on me. Brought it home and took apart and seemt the dovetail was loose. The blue loctite was old and had been frozen a couple times so thought it might be bad so went to ctc and got some new stuff, but in the meantime started a return to amazon for the one I had bought as the dovetail did not fit tight. I ordered a Burris unit

To check it out I remounted the amazon unit on the gun using the new blue loctite. Today the new burris ount came in and so went to take the old one off. The blue loctite did its job and the one screw came out but the other one stripped the allan hole trying to undo it. Now I have this red dot mounted on the gun with one stripped screw.

Anyone have ideas on how to get that small stripped allan screw out? I tried to use a #10 torx but it just made the stripped hole bigger. There is no room to get in a file a slot. I dont care about ruining the amazon mount but I really dont want to screw up the hole in the red dot that will be needed to mount on the new Burris mount.

Thoughts???

Look in the Gunsmithing Forum, and also on Hirsch Precision's Forum, where the was recently a similar, but not exact problem.

I just switched an optic tonight where the screws were secured with blue Loctite.

I tried to break them and they seemed really secure (due to the blue Loctite no doubt) so I took a punch with a tip that was a little smaller than the head of the screw that I was trying to remove, heated it up with a blow torch and then held it against the head of the screw. The heat transferred into the screw and softened up the Loctite to the point that I could remove it.

If the head is badly stripped your options are limited but you could try drilling a hole and using a screw extractor (wedge looking metal thing with a left hand thread - theory is you drill a hole just big enough to secure it and as you twist anti clockwise it gets tighter due to the taper and removes the stuck screw) or simply use a drill bit just a smidgen bigger than the threaded screw shank (guessing it is a countersunk head?) and you can drill until the tapered head is removed leaving the screw shank only which will allow you to remove the optic.

Good luck.

Thanks for all the help. Tried a bunch of it but in the end had to drill out the screw. Nice thing about allan screws is they supply a great piloy hole to drill through. Got it off and now installing the Burris Fast Fire mount.

Now this problem.

The Burris FastFire mount for glock comes with 2 dovetails as it can also set up on different pistols. The one dovetail felt loose in the slot and it was impossible to get the wider one into the dovetail. Anyone have experience with these? The instructions are decent but do not really spell out which dovetail is to be used in the Glock. There is a picture but it really is not clear.
