    That will work. It sounds like you have all the bases covered once you get the barrel nut off. Good luck.

    You can also machine off the barrel nut if you have already removed the front sight...
    So if I stick the barrel and all into the oven at 500º for half an hour or so that will defeat the loctite? Would I need to get it to a vice while it is still hot? If so I may try that if the heat gun does not work. Do not have access or the skill to machine it off but have thought about taking a dremel to it and seeing if I could cut it off without ruining the threads on the barrel.

    Thanks have planned this ever since I got the gun. Its my first AR so I ran it a year stock with just iron sights. Now I want to add a pistol fore grip, light and Aim point with BUIS. Thought it was going to be a whole lot easier than this and am disappointed that the stock parts are being destroyed in the process.

    You can ruin the anodizing if you leave it in the oven at 500

    get a mapp gas torch and heat up the barrel nut(apply heat evenly) with a wet cloth around the upper receiver and one around the barrel,then use your barrel nut wrench to remove the barrel nut.

    Dirty MOTHER #^*%!! I am so ticked off. Dinged the crap out of my Delta ring and the barrel nut is still stuck. Looks like I will have to cut the barrel nut off once it is unscrewed as it will not fit over the flash hider. Way more complicated than I expected any way end of rant and sniveling.
    Need a suggestion on an Action Block/Vise Block Set I found two. Any suggestion on which to get?
    ProMag Armorer's Upper & Lower Receiver Action Block Set AR-15

    Brownells Action Block/Vise Block Set
    Also any Delta ring suggestions? Any reason any would not fit on a Bushmaster?

    i would trust the set from brownell`s more,especially if you ever plan on more ar work!did you try heating the barrel nut with a torch and using wet towels on barrel and upper receiver?you will have to cut off your delta ring first!not sure if you need it or not,but they`re cheap.hope this helps!

    At this point why don't you chalk this up to a lesson learned and buy an upper from Grant and be done with it. Yes it sucks to have to spend even more money but do it right.

    I did heat the barrel nut and the barrel still spun me. Not quiet sure what you mean about the wet towels, what is the purpose of doing that? I'm game just curious as to why. Why cut off the delta ring? Not that it really matters as it is being replace anyway since I dinged the crap out of it. Again just curious.

    Any reason to not trust the ProMag Upper & Lower Receiver Action Block Set? I have bought from Brownells and Midway never had a problem with either, that I recall. But in this case Brownells prices for the Delta Ring Assembly Kit, and Upper & Lower Receiver Action Block Set is nearly double Midways price.

    Thanks for the input

    One idea I had. I have the removable carry handle that mounts on the top rail. Can I mount that on the receiver and stick the carry handle in the vise to hold the receiver? My concern is that I may torque the receiver. Anyone have any thoughts or opinions?

    the reason for the wet towels is to keep the barrel and upper receiver cool while heat is applied to the barrel nut.the reason i had for the delta ring being cut off is because you typically cant heat up the barrel nut without damage to the delta ring.the promag will work,but is of lower quality.without using a upper receiver block on a vise and trying to remove the barrel nut is not advised because it can cause damage to your upper receiver.you say your barrel is spinning.are you just trying to remove(undo)the barrel nut only by using an ar armorer `s wrench to the barrel nut?there is a raised metal nipple which fits in the upper receiver that is built into the barrel(i forget the technical name)that aligns the barrel into the upper receiver.this prevents the barrel spin when removing the barrel nut.the barrel should not spin at all!for the barrel to spin.the alignment nipple would have to be broken off. otherwise,if the barrel only is spinning,you would have to be trying to remove the barrel by just using a vise or clamping device on the barrel only causing it to spin off from the chambered part of the barrel put together by the barrel maker. obviously,that is not the correct way to remove the barrel.if this is the case,stop!bring this in to a qualified gunsmith that does ar work!this all should really be no big deal to remove.the couple of dollars for the gunsmith to do this for you will be nothing compared to the stress you`ve already been through!just tell the gunsmith what you tried,what it`s doing,and what you want accomplished.this may be your cheapest route also.i really wish you luck and hope anything advice i send will help!
