    Castle Nut Wrench

    Just wondering if anyone has one that they might be willing to lend me for a day or two? I want to put a single point sling endplate on my AR, but don't want to have to spend 30+ bucks on a wrench I'll use once. So if you have one and won't miss it for a short bit, I'll slip whatever shipping cost you in the package back to you when I'm done. Thanks.

    PS is there anything to really be worried about when taking off that castle nut? or replacing that endplate?

    never mind, found a cheaper endplate and justified just buying a wrench for myself to have. A good deal got the better of me I think! Oh well thanks anyways fellas.

    Some of them are held on with thread locking compound and need to be heated. A hair dryer on high will work in a pinch but a heat gun works better. I'm not ballsy enough to hold a torch to the aluminum but I'm told it works fast. Some of them are staked in and you may need to dremel down the stakes before it will break free. And then there are the nuts that the Incredible Hulk put on and with no thread lock or stakes it will take every ounce of backside you have to get loose, so spray some penetrating oil on there and let it soak for a while. I swore I was going to warp the frame from how much effort it took to get mine off. I put a drop of red Locktite on mine and then set it. Added an Ace shorty to her. The red will need some heat to break free but I don't plan on needing to replace it.
    It's a trick... Get an axe...

    Well I got the stuff i ordered from CTD today, and set in to change the receiver end plate. 20 minutes later and a lot of explitives I had the buffer tube/receiver extension, that was hard!!! I ended up having to use my fiancee's hair drier on the castle nut for about 5 minutes then torque the hell out of it. Thought I was gonna break myself or the wrench. I marred the castle nut a bit, but it's a rifle and a tool so I'm not too worried about that.

    Getting it back together was a whole nother story! Well not really I fought pretty hard with it too. If I had a vise this whole process would have been much easier. I ended up twisting the retaining pin spring about 3 coils from the end, so I just snipped those coils and put 'er back together. The pin still has plenty of tension on it, so I'm not worrying the rifle "breaking" in half on me. I'll order another spring the next time I order just to have it around, in case my quick fix doesn't hold for some reason.

    I'm hoping to get to go to the range as I also got a CMMG .22lr conversion kit, and need to also zero my new optic. In other words got a lot of work to do on this rifle at the range.
