This will let people with these uppers shoot .22 Long Rifle ammunition in addition to 5.7x28mm ammo. <\/p>\n\n\n\n<p>CMMG offers a range of conversion uppers chambered for 5.7x28mm that convert standard AR-15 lowers to shoot the popular personal defense weapon cartridge. With these kits the same uppers can fire inexpensive rimfire ammo, too. <\/p>\n\n\n\n<p>This way shooters can practice and plink using the same uppers, optics and accessories but at a lower cost in the long run. The kit uses conversion magazines that work with MIL-SPEC and compatible lower receivers, like CMMG&#8217;s 5.7mm conversion magazines. <\/p>\n\n\n\n<p>&#8220;Converting any CMMG Mk57 upper to shoot .22LR is a great way to reduce cost with each pull of the trigger, all while reducing recoil and muzzle flash,&#8221; said CMMG in the announcement. &#8220;Anyone who is interested in 5.7x28mm. but concerned about ammo prices, can take advantage of cost-effective rimfire training. It\u2019s the ultimate tool for young or first-time shooters.&#8221;<\/p>\n\n\n\n<p>The Mk57 .22 LR AR Conversion Kit will work with all of CMMG&#8217;s 100, 200 and 300 series 5.7mm upper receivers. These uppers are offered in a handful of different configurations with 5-, 8- and 16-inch barrels. <\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"904\" height=\"488\" title=\"CMMG Announcing Mk57 .22LR Conversion Kit\" src=\"https:\/\/www.gunsamerica.com\/digest\/wp-content\/uploads\/2020\/08\/57B3MAG.jpg\" alt=\"CMMG Announcing Mk57 .22LR Conversion Kit\" class=\"wp-image-133074\" srcset=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2020\/08\/57B3MAG.jpg 904w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2020\/08\/57B3MAG-400x216.jpg 400w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2020\/08\/57B3MAG-150x81.jpg 150w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2020\/08\/57B3MAG-768x415.jpg 768w\" sizes=\"(max-width: 904px) 100vw, 904px\" \/><figcaption>CMMG&#8217;s 5.7mm uppers also work with standard AR-15 and compatible lowers.

Standard magazine capacity is 25 rounds for .22 LR and reduced capacity compliant magazines are also available. The kit with one mag carries a $199 suggested retail price while the kit with three mags runs $229. <\/p>\n\n\n\n<p>Additional magazines run $24 so the three mag kit offers a solid value for only $30 more. Of course, to use them you&#8217;ll also need a Mk57 upper.<\/p>\n\n\n\n<p>Pricing for CMMG Mk57 uppers starts at $724, which is not inexpensive but in-line with other similar AR-15 upper receivers. CMMG also offers 5.7x28mm bolt assembly and barrel kits for builders that start at $399, giving shooters a lot of options in order to get into 5.7mm AR-pattern rifles and pistols. <\/p>\n\n\n\n<p>For
