Striped out Screw Need advice

[ScottSpreyNprey77]

Hello I have a AGD MM/AA rail and it has a striped out foregrip screw. I have tryied almost everything in the book to get this thing out. I have used drill bit that is soposed to back the screw out when i put a drill in reverse. It didnt work it only made things worst. The bit actualy heated up to the point where the metal from the bit melted and fused into the striped hole in the screw. Anyways any advice would be apprecieted.

ummmm... a standard AM/MM rail is not threaded... AT ALL. The back screw goes through into the valve and the front screw goes through into the body.

So if you have a screw stuck IN the rail you have issues.

The resolution??? ummmm... I would think using a chain braker to try and press it out may be something to try.

That or a big (my bad) hammer and good solid punch. Once you get it moving it should come on out, but getting it that first step may take a minute.

Good luck!!!

My bad!!!! I read FORWARD screw... Not FOREGRIP... That is also a pass through bolt though but my guess is you have a foregrip installed.

The next thing to do would be get a good sharp drill bit the size of the head of the screw and drill off the head. You can also use a cutting wheel to cut a notch into it to use a flat screwdriver in, but chances are you'll muck up the rail a bit doing it. Though it's nothing that will be seen when it's together....

Also try putting it in a freezer for a day.... pull it out and smack it really hard with another chunk of metal... then try and unscrew it out.

Let me know if none of that works...

So now you have an EZ OUT stuck in the bolt head? Can you screw it IN to try and get it out again??? Or is it IN there for good? If you get it out, just use a drill bit to drill off the top of the bolt. If you can't get it out, put it in the freezer for a day or over night. Get it out and smack it on the end of the EZ OUT like you are driving it in deeper a couple of times. Make it "PING" when you do. Sometimes the shock will break the stiction loose.

If you can't get it out any other way, just throw it away and go to the marker section and look at the guns I just listed and buy one of those...

Here's how I got mine out (bought a rail cheap which had TASO foregrip apparently super-glued and rusted-in, and the bolt was stripped in a failed attempt to get it out it seems):

Hold the screw on the rail under the running hot water 5-8 min (head of the screw and top of the foregrip/vert ASA as well), then pour a sink full of hot water and drop the rail there for a few min. Once you soak it good:
a) If there is an ASA: Stick a long screwdriver into the side output hole of the asa and gently but firmly rock ASA side to side to relax it from the rail a little and remove any glue that might hold it. Keep rocking and splashing in hot water, then do again, until it rocks pretty good.

Then try to find allen wrench a bit bigger than the original size or whatever kind of fits, and under water try to unscrew it - it will bulge abd you should get it out no problem, just keep it soaked hot! If you have foregrip instead of asa - hold it firm and rock side to side.

b) The hole in the screw is completely round and there's no way ANY allen screw will have some kind of a grip on it:
Get a dremel with cut-off wheel, try to make some notches on the screw to make it quasi-flathead (you will probably scratch the rail very-very lightly, but it's not noticeable when assembled and bears no difference in performance whatsoever). Then repeat the steps in a) using flathead instead of allen wrench.

Hope you get that sucker out!

Yeah, it may have some loctite on it, so some heat like a heat gun or lighter would help with that. Boiling water may be enough if you tried hot water already.

Is the screw actually stuck in the front ASA and what type of finish does the screw have (bright plate, black oxide, stainless)?

I will try all these methoods that you guys listed. I have time to work on my mag this weekend. I will let you know the results. Thank you very much for all the help.

Or before you make a mess of it, send it to me and for a small fee I'll remove it. If you bugger it up first, don't bother asking.
