Let&#8217;s chop it off.<\/p><\/div>\n<p>My AR-15 is a Frankenstein\u00a0gun. It&#8217;s got parts from at least five different guns I&#8217;ve owned. Overall, I like it, but the one thing that bugs me is the A2-style gas block. It&#8217;s that huge triangle at the front of the handguard. It was designed to be the front iron sight combined with the carry-handle rear sight. Now I&#8217;ve got a scope on my gun. The front sight actually sticks up in front of the scope, and while it&#8217;s visible, it doesn&#8217;t negatively affect the view through the scope.<\/p>\n<p>I have to admit that my annoyance toward the A2 gas block is purely cosmetic. Still, it&#8217;s gotta go.<\/p>\n<h2>Why not just buy one?<\/h2>\n<p>You could simply buy a new low-profile gas block and install it on your AR, but if there&#8217;s one thing that&#8217;s almost as much fun as using explosives to launch projectiles from your gun, it&#8217;s making tons of sparks and pretending to be a metal worker. So, yeah, a new gas block would only cost about $30, but this is a fun project that&#8217;ll take less than an hour. Heck, if you want to, you could take the $30 and spend it on the tools to get this done and end up with a low profile gas block and a few handy tools.<\/p>\n<div id=\"attachment_107432\" style=\"width: 1034px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/www.gunsamerica.com\/digest\/wp-content\/uploads\/2019\/03\/A2-Sight-to-low-profile-3-1.jpg\" target=\"_blank\" class=\"clickTracking\" campaign=\"diy-convert-your-a2-gas-block-to-a-low-profile-gas-block\" title=\"DIY: Convert Your A2 Gas Block to a Low Profile Gas Block\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-107432\" title=\"One-Handed Shooting: Let It Tilt 10 O\u2019Clock High\" class=\"size-large wp-image-107432\" src=\"https:\/\/www.gunsamerica.com\/digest\/wp-content\/uploads\/2019\/03\/A2-Sight-to-low-profile-3-1-1024x576.jpg\" alt=\"One-Handed Shooting: Let It Tilt 10 O\u2019Clock High\" width=\"1024\" height=\"576\" srcset=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2019\/03\/A2-Sight-to-low-profile-3-1-1024x576.jpg 1024w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2019\/03\/A2-Sight-to-low-profile-3-1-150x84.jpg 150w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2019\/03\/A2-Sight-to-low-profile-3-1-400x225.jpg 400w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2019\/03\/A2-Sight-to-low-profile-3-1-768x432.jpg 768w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2019\/03\/A2-Sight-to-low-profile-3-1.jpg 1200w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/a><p id=\"caption-attachment-107432\" class=\"wp-caption-text\">You need to remove these three pins in order to detach the gas block from the barrel.<\/p><\/div>\n<h2>What you need<\/h2>\n<p>You&#8217;re going to need a few specific tools.

This is for the roll pin that holds the gas tube in place. You could use a roll pin punch, but it&#8217;s not totally necessary. A straight 1\/16&#8243; punch will do it. I bought one for $2.49, but you can get a whole set of punches under $10. You can use the tiny punch to work on the bigger pins, but a larger punch, like 3\/16&#8243; is better. Get the whole pouch of punches.<\/li>\n<li>Lightweight hammer<\/li>\n<li>Grinder, or another cutting tool. You could probably do this with a hack saw, but you&#8217;d be missing out on the sparks. A cheap right angle grinder will cost you less than $30. A bench grinder will work, too. Alternatively, you could get disks for a drill or a Dremel tool.<\/li>\n<li>Clamp or vice<\/li>\n<li>File, emery paper or brush for burs.

Remove the roll pin<\/h2>\n<p>The first thing you need to do is remove the roll pin that keeps the gas tube in place. Use the scrap wood to prop up the sight and support the rest of the gun: The idea is to make sure your force is all applied to the pin, and not to another part of the gun&#8211;like the scope. Prop it up and leave space behind the pin to push it out. The gun should be oriented so its left side is up, probably with the barrel pointing to your left.<\/p>\n<p>Use the 1\/6&#8243; punch to push the roll pin out. Use a small hammer so you don&#8217;t apply too much force. The thing to avoid is deforming the roll pin, but don&#8217;t be too dainty with it, either. You might even apply a little CLP to the pin and let it set a minute to help it loosen up. Once it&#8217;s out, keep the pin oriented so you know which way it was in the hole so you can put it back that way. Oh, and don&#8217;t lose it.<\/p>\n<div id=\"attachment_107417\" style=\"width: 1034px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/www.gunsamerica.com\/digest\/wp-content\/uploads\/2019\/03\/A2-Sight-to-low-profile-5.jpg\" target=\"_blank\" class=\"clickTracking\" campaign=\"diy-convert-your-a2-gas-block-to-a-low-profile-gas-block\" title=\"DIY: Convert Your A2 Gas Block to a Low Profile Gas Block\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-107417\" title=\"One-Handed Shooting: Let It Tilt 10 O\u2019Clock High\" class=\"size-large wp-image-107417\" src=\"https:\/\/www.gunsamerica.com\/digest\/wp-content\/uploads\/2019\/03\/A2-Sight-to-low-profile-5-1024x576.jpg\" alt=\"One-Handed Shooting: Let It Tilt 10 O\u2019Clock High\" width=\"1024\" height=\"576\" srcset=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2019\/03\/A2-Sight-to-low-profile-5-1024x576.jpg 1024w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2019\/03\/A2-Sight-to-low-profile-5-150x84.jpg 150w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2019\/03\/A2-Sight-to-low-profile-5-400x225.jpg 400w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2019\/03\/A2-Sight-to-low-profile-5-768x432.jpg 768w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2019\/03\/A2-Sight-to-low-profile-5.jpg 1200w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/a><p id=\"caption-attachment-107417\" class=\"wp-caption-text\">Use a little masking tape to add a little grip for your punch to keep from slipping off and marring the surrounding metal.<\/p><\/div>\n<h2>2.

Trim the sight off<\/h2>\n<p>Now you&#8217;re ready to cut off the top of the block. Lock it down in a vice, or clamp it to an edge and get to work. Just a few things to remember: Don&#8217;t get so excited making sparks that you trim too much&#8211;the gas tube still has to go back in there, so don&#8217;t trim into its cavity. Also, take a look and make sure you trim it low enough to fit under the handguard. I&#8217;ll probably get a rifle-length handguard in the future, so I want it to fit under that. Lastly, I was surprised at how easily the metal cut away so start gently and work into it.<\/p>\n<p><span data-mce-type=\"bookmark\" style=\"width: 0px;overflow: hidden;line-height: 0\" class=\"mce_SELRES_start\">\ufeff<\/span><\/p>\n<p>Be careful&#8211;it&#8217;s hot from grinding.<\/p>\n<h2>5.

This is purely cosmetic&#8211;you could just assemble the gun back together, but you&#8217;ll be glad to have smooth edges in the long run.<\/p>\n<h2>6. Paint or blue the block<\/h2>\n<p>The raw steel you&#8217;ve exposed is now susceptible to rust. You should paint or use some bluing agent to protect the steel. I chose to paint it, but I think if I did it again I&#8217;d buy some bluing (like that from Birchwood Casey) because I think it will have better coverage.
