bolt striped how to take it out

recently i managed to strip one of the bolts on the a-5 the one near he  barrel the top one which u need to take off to switch the barrel and to clean it, i can still change the barrel with unscrewing the buttom one and the other big bolt but i cant open the gun b/c of this its so bad i cant use a bigger device to open it. what do you suggest i do, drill it out with a drill press or?

And after thats done, go buy some high quality allen wrenches so it doesnt happen again.

the t handles one's or the regular ones

use a 7/32" drill bit and drill dead center of the stripped out head, when you get deep enough the head will simply fall off. you can then remove the half of the gun and remove what's left of the bolt with a vise grip. if at any time you see aluminum drilling out stop! you are deep enough

Eklind makes quality allen wrenches

Of course it didn't work. Where did you get the idea that super glue would work...other than in a sarcastic post I made about someone who ignored the JB Weld epoxy recommendation.

Okay, did you read and understand what Tigman250 just posted right here on this subject??? READ IT AGAIN! After you do, if you still think it a good idea to drill all the way until you see "the drill bit through the other side." When you do, then please do not come back and ask what to do because the new bolt's head just drops through the hole.

Exactly! But, if the JB Weld was not used at the first attempt of removal of the bolt, the Allen socket may be contaminated so that the JB won't bond strongly enough to do the job. Also the JB Weld method may fail even in the best situations if the bolt was excessively over-tightened in the first place. Then it becomes time to revert to the other methods that have been shown to work.

One of the best "second" tries is to obtain a left handed drill bit (industrial supply places) and use it in a reversible drill. The process of drilling out the head of the bolt may bite into the bolt well enough to back it out of the receiver. Here is a crude diagram:

And, as posted by Tigman 250, lift off the shell and use vise grips to unscrew the bolt. Or you could then just whack it lightly with a hammer to drive the nut out with it. Then replace both the nut and bolt with new ones.

I understand. I TIG weld aluminum fuel tanks myself, but the bolt is going to be thrown away...not repaired.
