Separate the upper from the lower receiver. Remove the bolt carrier group. Use wooden blocks to pad the upper and help you secure it in the vise.

Then the barrel nut goes over the barrel and threads onto the upper which pulls the barrel tight against the upper. Another way to do it is the way Unique ARs does it. The barrel nut goes onto the upper, then the barrel is pulled into the receiver using a castle nut which threads into the barrel nut.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"512\" title=\"DIY: Upgrade Your AR Handguard!\" src=\"https:\/\/www.gunsamerica.com\/digest\/wp-content\/uploads\/2019\/08\/Unique-ARs-Handguard-Levi-Sim-7-1024x512.jpg\" alt=\"DIY: Upgrade Your AR Handguard!\" class=\"wp-image-114256\" srcset=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2019\/08\/Unique-ARs-Handguard-Levi-Sim-7-1024x512.jpg 1024w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2019\/08\/Unique-ARs-Handguard-Levi-Sim-7-150x75.jpg 150w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2019\/08\/Unique-ARs-Handguard-Levi-Sim-7-400x200.jpg 400w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2019\/08\/Unique-ARs-Handguard-Levi-Sim-7-768x384.jpg 768w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2019\/08\/Unique-ARs-Handguard-Levi-Sim-7.jpg 1200w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption>From left to right: barrel, castle nut, barrel nut, upper receiver threaded extension.<\/figcaption><\/figure>\n\n\n\n<p><\/p>\n\n\n\n<p>This is where the armorer&#8217;s wrench comes in. There&#8217;s just no other tool you can use that won&#8217;t ruin the barrel nut&#8217;s threads. Some new barrel nuts include flat surfaces so you can use an adjustable wrench, and I think those are great. But, for the barrel nut on my gun and for the castle nut from Unique ARs, an armorer&#8217;s wrench is necessary.<\/p>\n\n\n\n<p>You can buy cheap wrenches for about $20 from Amazon or eBay. You&#8217;ll see reviews that say they are garbage and reviews that aren&#8217;t specific but give 5 stars. The 5-star reviews were paid for and the person probably didn&#8217;t use the wrench. Pay attention to the reviews that say the wrench was cheap metal that bent and wasn&#8217;t usable. If you pay about $60 you can get a quality wrench from someplace like Brownell&#8217;s. Or, you can borrow your buddy&#8217;s wrench (as I did here). <\/p>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"768\" title=\"DIY: Upgrade Your AR Handguard!\" src=\"https:\/\/www.gunsamerica.com\/digest\/wp-content\/uploads\/2019\/08\/Unique-ARs-Handguard-Levi-Sim-8-1024x768.jpg\" alt=\"DIY: Upgrade Your AR Handguard!\" class=\"wp-image-114257\" srcset=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2019\/08\/Unique-ARs-Handguard-Levi-Sim-8-1024x768.jpg 1024w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2019\/08\/Unique-ARs-Handguard-Levi-Sim-8-150x113.jpg 150w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2019\/08\/Unique-ARs-Handguard-Levi-Sim-8-400x300.jpg 400w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2019\/08\/Unique-ARs-Handguard-Levi-Sim-8-768x576.jpg 768w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2019\/08\/Unique-ARs-Handguard-Levi-Sim-8.jpg 1200w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption>There&#8217;s just no getting around it: you&#8217;re going to need an armorer&#8217;s wrench to remove the barrel nut from a classic AR.

I had to get my entire weight behind it to break it loose. Remember to keep an eye on the vise and make sure you don&#8217;t deform the upper.

It&#8217;s a good opportunity to clean the barrel extension and the barrel. Also, clean grease or oil off the threaded upper receiver extension.

The barrel nut goes onto the upper first. Thread it on and off once or twice to make sure the threads are clear and smooth. Also, make sure it&#8217;s going on in the right direction so the handguard can slide on. <\/p>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"768\" title=\"DIY: Upgrade Your AR Handguard!\" src=\"https:\/\/www.gunsamerica.com\/digest\/wp-content\/uploads\/2019\/08\/Unique-ARs-Handguard-Levi-Sim-10-1024x768.jpg\" alt=\"DIY: Upgrade Your AR Handguard!\" class=\"wp-image-114260\" srcset=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2019\/08\/Unique-ARs-Handguard-Levi-Sim-10-1024x768.jpg 1024w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2019\/08\/Unique-ARs-Handguard-Levi-Sim-10-150x113.jpg 150w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2019\/08\/Unique-ARs-Handguard-Levi-Sim-10-400x300.jpg 400w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2019\/08\/Unique-ARs-Handguard-Levi-Sim-10-768x576.jpg 768w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2019\/08\/Unique-ARs-Handguard-Levi-Sim-10.jpg 1200w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption>The gas ports on the barrel nut and the receiver must line up.

Unscrew the nut and add a drop of blue Loctite to the threads (Loctite comes in different colors for different uses&#8211;blue can be more easily removed for service later). Tighten the nut back into place so the gas port holes align. Allow the Loctite to dry for at least a couple of hours, maybe even a whole day.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"768\" title=\"DIY: Upgrade Your AR Handguard!\" src=\"https:\/\/www.gunsamerica.com\/digest\/wp-content\/uploads\/2019\/08\/Unique-ARs-Handguard-Levi-Sim-11-1024x768.jpg\" alt=\"DIY: Upgrade Your AR Handguard!\" class=\"wp-image-114261\" srcset=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2019\/08\/Unique-ARs-Handguard-Levi-Sim-11-1024x768.jpg 1024w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2019\/08\/Unique-ARs-Handguard-Levi-Sim-11-150x113.jpg 150w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2019\/08\/Unique-ARs-Handguard-Levi-Sim-11-400x300.jpg 400w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2019\/08\/Unique-ARs-Handguard-Levi-Sim-11-768x576.jpg 768w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2019\/08\/Unique-ARs-Handguard-Levi-Sim-11.jpg 1200w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption>It&#8217;s not totally necessary, but using thread locker on the barrel nut can make it easier to keep the gas ports aligned when you torque the castle nut. <\/figcaption><\/figure>\n\n\n\n<p><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Attach Barrel <\/h2>\n\n\n\n<p>Now you can attach the barrel with the castle nut.

I applied another drop of Loctite, but it&#8217;s probably not necessary. <\/p>\n\n\n\n<p>It&#8217;s important that you keep the gas port holes aligned.
