    i will give her the old college try but i’m not optimistic. that little bitty screw hasn’t budged. if freezing the wrench does the trick i will do a flat footed backflip

    Since aluminum expands at nearly twice the rate of steel cooling the set screw probably won’t be a big deal.


    But if it’s got locktight on it it’s gonna have to get hot enough to break down or it won’t matter much. 350-450 degrees depending on type and breaking down the loctite will matter a lot more than the expansion rates.

    considering all the time & money i have in the diy blasting, prep & cerakote finish i don’t have intentions of damaging my “paint”

    oth, it did bake at 350-degrees to cure. now if that means my lower can take another 350+ before the cerakote is adversely affected, i will have to research. i did put the propane torch to it a few times thinking that would be enough.

    after all, i watched some videos of a guy breaking Loctited screws with nothing more than the allen wrench heated red hot. i heated my tiny allen wrench red hot & ruined it. i don’t have the luxury of turning on screws that are a good 5/16 or larger.

    this was blue loctite i used - never had a problem before. i have to loctite every screw on this 308. otherwise i would leave the target practice & literally get home without all of my screws. EVERYTHING came loose the 1st few times — couldn’t hit the targets..
    oh my r/d optic is falling off. won’t cycle properly.. oh the buffer tube is about fall out. this is the only screw i’ve had a problem with. prob bc nothing fits perfectly or won’t let me get straight on in order to put some a$$ into the wrench

    ps tried to post short video and file was too large to upload. whatever shall i do! the forum members won’t get to see me lose my $hit over a 2mm screw. oh well!

    Can you use a small left handed bit & drill it out? Need a long bit or an extension of some sort.

    Easy out might help.

    When I have to deal with stuck screws I throw the whole thing in the freezer first. The screw will contract and the receiver may contract away from the screw.

    Driving a bit bigger wrench/ Torx head in is always helpful too. The bigger tool and the hitting action definitely help.

    ya the screw head is too small. i tried the impact and it just bent the wrench. heating it cherry red set me up for failure. $7 wrench/socket that i have cut in half, twisted & bent up to this point.

    Throw the entire lower in the freezer over night. Hold some torque on the screw while heating the receiver with a torch, and have someone hit the receiver with a dead-blow hammer over the screw housing area?

    The lower should warm up and expand a lot faster than the steel of the screw.

    36DD5B5E-04E7-46D0-A19A-D266D1DEE301.png i don’t know what will happen of the cerakote in regards to freezing it for hours on-end.

    i have been prudent in the use of a propane torch & open flames near it along with the length of time, choosing to focus the heat/flame mostly to the steel bolt catch.

    i don’t know what a micro torch is - how much does it differ from what i have in the pics posted earlier?

    anything i do to remove the screw is secondary to protecting the finish. it can handle up to 500-deg but holding an open flame to it is no temp controlled oven.
