Ammo is cheaper than 5.56 and more than likely you can use the same ammo you use in your 9mm EDC gun in your AR. Converting your 5.56 NATO AR to 9mm is a really simple AR hack, especially if you buy a complete 9mm upper. And you will want to buy a complete upper since some are relatively inexpensive. You can have your 5.56 AR shooting 9mm as fast as field stripping your gun.<\/p>\n\n\n\n<div class=\"wp-block-yoast-seo-table-of-contents yoast-table-of-contents\"><h2>Table of contents<\/h2><ul><li><a href=\"#h-how-do-you-convert-an-ar-15-to-shoot-9mm-nbsp\" class=\"clickTracking\" campaign=\"shoot-9mm-out-of-your-ar-15\" title=\"Shoot 9mm Out Of Your AR-15\" data-level=\"2\">How Do You Convert An AR-15 to Shoot 9mm?\u00a0<\/a><\/li><li><a href=\"#h-colt-vs-glock-ar-15-adapter\" class=\"clickTracking\" campaign=\"shoot-9mm-out-of-your-ar-15\" title=\"Shoot 9mm Out Of Your AR-15\" data-level=\"2\">Colt vs Glock AR-15 Adapter<\/a><\/li><li><a href=\"#h-mag-options\" class=\"clickTracking\" campaign=\"shoot-9mm-out-of-your-ar-15\" title=\"Shoot 9mm Out Of Your AR-15\" data-level=\"2\">Mag Options<\/a><\/li><li><a href=\"#h-bcg-for-a-9mm-ar-15\" class=\"clickTracking\" campaign=\"shoot-9mm-out-of-your-ar-15\" title=\"Shoot 9mm Out Of Your AR-15\" data-level=\"2\">BCG For A 9mm AR-15<\/a><\/li><li><a href=\"#h-use-a-heavy-buffer\" class=\"clickTracking\" campaign=\"shoot-9mm-out-of-your-ar-15\" title=\"Shoot 9mm Out Of Your AR-15\" data-level=\"2\">Use A Heavy Buffer<\/a><\/li><li><a href=\"#h-complete-upper\" class=\"clickTracking\" campaign=\"shoot-9mm-out-of-your-ar-15\" title=\"Shoot 9mm Out Of Your AR-15\" data-level=\"2\">Complete Upper<\/a><\/li><li><a href=\"#h-aimpoint-acro-p-2-red-dot\" class=\"clickTracking\" campaign=\"shoot-9mm-out-of-your-ar-15\" title=\"Shoot 9mm Out Of Your AR-15\" data-level=\"2\">Aimpoint ACRO P-2 Red Dot<\/a><\/li><li><a href=\"#h-firing-up-the-9mm-ar-15-conversion\" class=\"clickTracking\" campaign=\"shoot-9mm-out-of-your-ar-15\" title=\"Shoot 9mm Out Of Your AR-15\" data-level=\"2\">Firing Up The 9mm AR-15 Conversion<\/a><\/li><li><a href=\"#h-is-a-9mm-ar-15-conversion-worth-it\" class=\"clickTracking\" campaign=\"shoot-9mm-out-of-your-ar-15\" title=\"Shoot 9mm Out Of Your AR-15\" data-level=\"2\">Is A 9mm AR-15 Conversion Worth It?<\/a><\/li><\/ul><\/div>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"578\" src=\"https:\/\/www.gunsamerica.com\/digest\/wp-content\/uploads\/2024\/05\/IMG_3792-1024x578.jpg\" alt=\"an ar15 converted to shoot 9mm\" class=\"wp-image-202517\" srcset=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2024\/05\/IMG_3792-1024x578.jpg 1024w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2024\/05\/IMG_3792-400x226.jpg 400w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2024\/05\/IMG_3792-150x85.jpg 150w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2024\/05\/IMG_3792-768x433.jpg 768w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2024\/05\/IMG_3792.jpg 1200w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-how-do-you-convert-an-ar-15-to-shoot-9mm-nbsp\">How Do You Convert An AR-15 to Shoot 9mm?&nbsp;<\/h2>\n\n\n\n<p>All you need are four parts to get running: a complete 9mm upper, buffer, magazine well adapter, and magazines.

There are some adapters that feed off Beretta 92 or S&amp;W M&amp;P magazines, but the Glock and Colt types are the most popular. The Colt pattern magazines are all steel; Glock style are polymer. The Colt 9mm rifle was the original AR-15 designed to utilize stick magazines that are actually modified Uzi type 32-round magazines. Glock magazines are found nearly every where, and come is variety of round counts from anemic 10-round magazines to obese 33-round magazines. <\/p>\n\n\n\n<p>Plus non-OEM Glock magazines are compatible, too. One thing to note if you opt for either Glock or Colt magazines, your BCG needs to be compatible with your magazine choice, which I\u2019ll get into.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"768\" src=\"https:\/\/www.gunsamerica.com\/digest\/wp-content\/uploads\/2024\/05\/IMG_3810-1024x768.jpg\" alt=\"9mm magazines for an Ar15\" class=\"wp-image-202520\" srcset=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2024\/05\/IMG_3810-1024x768.jpg 1024w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2024\/05\/IMG_3810-400x300.jpg 400w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2024\/05\/IMG_3810-150x113.jpg 150w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2024\/05\/IMG_3810-768x576.jpg 768w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2024\/05\/IMG_3810.jpg 1200w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">From left to right: KCI 33-round Glock style magazine, 33-round Glock OEM magazine, 21-round Magpul PMAG GL9 Glock style magazine, and 32-round Colt-style magazine.<\/figcaption><\/figure>\n\n\n\n<p>The adapter or conversion block is a part that fits inside the existing 5.56 NATO magazine well.

The difference is that it installs from the bottom of the magwell, as if you were inserting a magazine into your AR. A set screw and the magazine catch hold the adapter in place. <\/p>\n\n\n\n<p>The Stern Defense adapter has its own magazine release built in which is easily operated by the trigger finger of a right handed shooter. If you press the AR-15 magazine release, no worries. The Stern Defense adapter is locked it place, but easily removed by backing out the set screw.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"768\" src=\"https:\/\/www.gunsamerica.com\/digest\/wp-content\/uploads\/2024\/05\/IMG_3794-1024x768.jpg\" alt=\"stern defense 9mm adapter for glock\" class=\"wp-image-202525\" srcset=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2024\/05\/IMG_3794-1024x768.jpg 1024w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2024\/05\/IMG_3794-400x300.jpg 400w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2024\/05\/IMG_3794-150x113.jpg 150w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2024\/05\/IMG_3794-768x576.jpg 768w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2024\/05\/IMG_3794.jpg 1200w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"768\" src=\"https:\/\/www.gunsamerica.com\/digest\/wp-content\/uploads\/2024\/05\/IMG_3796-1024x768.jpg\" alt=\"stern defense glock magwell\" class=\"wp-image-202526\" srcset=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2024\/05\/IMG_3796-1024x768.jpg 1024w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2024\/05\/IMG_3796-400x300.jpg 400w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2024\/05\/IMG_3796-150x113.jpg 150w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2024\/05\/IMG_3796-768x576.jpg 768w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2024\/05\/IMG_3796.jpg 1200w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">The Stern Defense 9mm adapter uses the lower&#8217;s magazine catch and a set screw to secure the adapter.

Pistol caliber ARs use a direct blow back system. A 5.56 NATO AR uses a direct impingement (DI) gas system. The DI system pipes burning gases from a fired round at the muzzle through a gas tube. It goes into a gas key on the BCG to cycle the rifle. A blow back system uses the energy and the motion of the fired cartridge case to operate the BCG. There are differences in a 9mm BCG and 5.56 NATO BCG like the bolt face since the case rim of a 9mm round is different than the rim of a 5.56 NATO round.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"768\" src=\"https:\/\/www.gunsamerica.com\/digest\/wp-content\/uploads\/2024\/05\/IMG_3815-1-1024x768.jpg\" alt=\"glock magazine feed from the center, colt magazines feed from a double stack\" class=\"wp-image-202534\" srcset=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2024\/05\/IMG_3815-1-1024x768.jpg 1024w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2024\/05\/IMG_3815-1-400x300.jpg 400w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2024\/05\/IMG_3815-1-150x113.jpg 150w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2024\/05\/IMG_3815-1-768x576.jpg 768w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2024\/05\/IMG_3815-1.jpg 1200w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Glock style magazines (left) feed from the center, Colt-style magazines feed from a double stack.<\/figcaption><\/figure>\n\n\n\n<p>There are three types of 9mm BCGs, those cut for Glock magazine, those cut for a Colt magazine, and a hybrid that is compatible with both Glock and Colt magazines. A Glock compatible BCG feeds from a single stack at the feed lips of the magazine. A Colt compatible BCG feeds from a double stack at the feed lips. The portion of the bolt that pushes the case head of the cartridge into the chamber varies between the two. A hybrid BCG is cut to push cartridges from either a Colt or a Glock magazine.
