    Did you already chew up the wrench flats on the back of the receiver extension?

    I am using a mag block with the "proper wrench" on the receiver extension. The paperwork that came from "Magpul" with the stock states 35-39 ft lbs for installation.

    No the flats on receiver extension are in perfect shape, I have been using the correct armorers wrench.

    Would suspect the tube galled. The tube, receiver or both may get irreparably damaged trying to break this loose.

    UPDATE....with lessons to be taught and learned.
    1. Use the proper tools for the job
    2. Patients (walk away when frustration sets in and come back to it later) things never go well when angry/frustrated
    3. Repeat 1 and 2 until successful

    Receiver extension came loose with no damage to it or the lower receiver.
    After 3 days of effort with another cycle of heating and penetrating oil, it came loose.
    Thanks guys!

    Perfect on both the lower receiver and receiver extension. Your thoughts on thread gulling was a concern of mine as well, although again I installed the stock years ago and knew the receiver extension screwed in by hand and was torqued.
