    My Magpul comes tomorrow, so I figured I'd get the pinned stock off tonight.

    Holy hell did I make a mess of my stock trying to get the pins out. I read in a few different places that people were drilling into the pin until it would "bite" and then wiggling the pin out. Took a 1/8 bit and there was no aforementioned "Bite". It just shaved away the top of the pin. Then tried a 7/64 and the bit snapped before it did anything to the pin. Went back to the 1/8 and tried to just drill the pin out the other side. It was a no-go, bit snapped again. Moved up to the next bit size but could get through the 2 broken bits.

    Moved onto the SECOND pin...yes, they pinned it twice. This time I tried to drill through the pin right from the start using a fairly large bit (maybe a 3/16). I think I got through the first half of the pin, but AGAIN, snapped the bit once I hit the buffer tube. A handful of f-bombs later, I figured it might be easier to just swap the buffer tube, unless RRA decided to red loctite the castle-nut.

    I don't know what the hell was going on, but I've seen people drilling through these things like butter. Now I'm weary about trying to pin the new stock once I get a new tube. Hate to pay a gunsmith for something that should be pretty simple.

    /end rant

    Use an EZ out. They are used to remove broken screws.
    Use one a little smaller than the pin. It will bite into the roll pin, and compress it slightly so you should be able to remove it.

    I've used this method a couple of times.

    I believe that RRA does use thread lock compound, might want to heat it up with a heat gun before you try to loosen the castle nut.

    Good to know, just wish I had asked before I broke off multiple bits that are now lodged in the holes.
