They offer the brake in 5.56 and .30 caliber.<\/p><\/div>\n<p>In my never-ending quest to avoid the NFA licensing process, I opted in my most recent AR build to purchase a 14.5 inch Ballistic Advantage barrel and pin\/weld a 2 inch Daniel Defense muzzle brake to the end of it.<\/p>\n<p>It may not be the most practical option (I only saved about 2 inches of overall length), but I enjoyed the project and I think the barrel\/brake looks great with my 15 inch Rainer Arms rail.<\/p>\n<h2><strong>Step 1: Choose your Muzzle Device<\/strong><\/h2>\n<p>Keep two things in mind when choosing your muzzle device: barrel length and rail length. If you\u2019re using a muzzle brake, pick one that both meets or exceeds the 16 inch mark <em>and<\/em> one that will clear your rail.<\/p>\n<p>As the pin\/weld option is gaining popularity, many gun parts manufacturers offer brakes designed specifically for this purpose. Daniel Defense offers an extended version of their Muzzle Climb Mitigator to ensure the brake holes will clear a 15 inch rail. I\u2019ve also seen muzzle devices with a pre-drilled hole (more on that below).<\/p>\n<p>You can also use other muzzle devices (flash suppressors, flash cans, etc.) that direct the blast forward instead of upwards. In that case, your only concern will be to meet the 16 inch barrel + brake requirement.<\/p>\n<h2><strong>Step 2: Drill the Hole<\/strong><\/h2>\n<div id=\"attachment_78995\" style=\"width: 1210px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/www.gunsamerica.com\/blog\/wp-content\/uploads\/2017\/09\/Dremel.jpg\" target=\"_blank\" class=\"clickTracking\" campaign=\"diy-pin-weld-muzzle-brake\" title=\"DIY: How to Pin &amp; Weld a Muzzle Brake\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-78995\" title=\"DIY: How to Pin &amp; Weld a Muzzle Brake\" class=\"size-full wp-image-78995\" src=\"https:\/\/www.gunsamerica.com\/blog\/wp-content\/uploads\/2017\/09\/Dremel.jpg\" alt=\"DIY: How to Pin &amp; Weld a Muzzle Brake\" width=\"1200\" height=\"754\" srcset=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2017\/09\/Dremel.jpg 1200w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2017\/09\/Dremel-150x94.jpg 150w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2017\/09\/Dremel-400x251.jpg 400w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2017\/09\/Dremel-768x483.jpg 768w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2017\/09\/Dremel-1024x643.jpg 1024w\" sizes=\"(max-width: 1200px) 100vw, 1200px\" \/><\/a><p id=\"caption-attachment-78995\" class=\"wp-caption-text\">Be patient on this step.

This is a poor man\u2019s how-to guide (see title), which means I didn\u2019t have the fancy tools that are probably necessary for this job. But that\u2019s never stopped me before, and with the combination of a Dremel tool and a power drill I made it through eventually.<a href=\"https:\/\/www.gunsamerica.com\/blog\/wp-content\/uploads\/2017\/09\/Drill.jpg\" target=\"_blank\" class=\"clickTracking\" campaign=\"diy-pin-weld-muzzle-brake\" title=\"DIY: How to Pin &amp; Weld a Muzzle Brake\"><img loading=\"lazy\" decoding=\"async\" title=\"DIY: How to Pin &amp; Weld a Muzzle Brake\" class=\"aligncenter size-full wp-image-78996\" src=\"https:\/\/www.gunsamerica.com\/blog\/wp-content\/uploads\/2017\/09\/Drill.jpg\" alt=\"DIY: How to Pin &amp; Weld a Muzzle Brake\" width=\"1200\" height=\"800\" srcset=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2017\/09\/Drill.jpg 1200w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2017\/09\/Drill-150x100.jpg 150w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2017\/09\/Drill-400x267.jpg 400w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2017\/09\/Drill-768x512.jpg 768w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2017\/09\/Drill-1024x683.jpg 1024w\" sizes=\"(max-width: 1200px) 100vw, 1200px\" \/><\/a><\/p>\n<p>I opted to drill the hole before installing the muzzle device.
