Does any one know how to take these off. A friend of mine has purchased ad new synthetic one, and we are trying to figure out how to change it. Thanks in advance for any help you can provide.

    There is a special wrench required. Difficult to do otherwise.

    They are about $20. I HIGHLY recommend that you order one or take it to a gun shop. It will keep the nut just like new. Also, if you do manage to get it off and don't get it tightened properly (besides marking it up some) it can come off and the slide will malfunction.

    Also, wrap up the wood stock and keep it.

    There is also a trick to get by without the wrench but you will need to be carefull to make sure everything is secure. You are building a spanner wrench in a vice.

    You will need:

    (4) small blocks of wood 3/4" thick
    (2) flat blade screwdrive bits (long ones)
    (1) firmly mounted bench vice

    a. Open the vice about 2"
    b. using masking or scotch tape, place a bit between the edge of two of the blocks with the tip sticking up about 1/4" stright with the spaced between the blocks and tape them together.
    c. make another bit and block assembly left hand and tape it also.
    d. measure the width of the slots in the nut on the end of the forearm stock.
    e. set the two wood block/bit assemblies in the vice with a gap between them so that the magazine tube will just fit between them and the bits will align perfectly with the slots in the nut.
    f. tighten the vice on the blocks and bits.
    g. put some tape around the magazine tube to prevent and scratches.
    h. make sure it all lines up well with the nut


    If you can picture what I just said, you should now have a rigid spanner wrench to remove and replace the nut.

    The actual wrench or the gunshop is still my recommendation, however.

    An AR15 stock wrench will also work, but be careful not to slip and scratch your finish.
