Each rifle has a 16.5&#8243; barrel and is chambered in either 5.56x45mm or 7.62x51mm NATO, as you could have guessed. <\/p>\n\n\n\n<p>The pistol is chambered in 5.56x45mm NATO and has an 11&#8243; barrel.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-rifle-details\">Rifle Details<\/h2>\n\n\n\n<p>The MR A4 line only differs from the Hk416 because they don&#8217;t come with a chrome-lined barrel. Otherwise, these firearms come with all of the features that you would expect, including a fully ambidextrous design. <\/p>\n\n\n\n<p>The new 45\u00b0 safety is ambi on both sides, as are the mag release and bolt release. Despite not having a chrome-lined barrel, HK is so confident in its durability that they offer a <a href=\"https:\/\/gunsamerica.com\/digest\/taurus-lifetime-warranty\/\" target=\"_blank\" class=\"clickTracking\" campaign=\"hk-mr-a4-hk416-performance-for-anyone-shot-show-2025\" title=\"HK MR A4: HK416 Performance For Anyone -- SHOT Show 2025\"  data-wpil-monitor-id=\"2905\">lifetime warranty<\/a> on the barrel\u2014if you shoot it out, they\u2019ll replace it for free!<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-see-also-b4-armory-css-briefcase-rifle-shot-show-2025\">SEE ALSO: <a href=\"https:\/\/www.gunsamerica.com\/digest\/b4-armory-css-briefcase-rifle-shot-show-2025\/\" target=\"_blank\" class=\"clickTracking\" campaign=\"hk-mr-a4-hk416-performance-for-anyone-shot-show-2025\" title=\"HK MR A4: HK416 Performance For Anyone -- SHOT Show 2025\">B4 Armory CSS \u2018Briefcase\u2019 Rifle \u2014 SHOT Show 2025<\/a><\/h2>\n\n\n\n<p>What really sets the MR A4 apart is its short-stroke gas piston system. This system doesn\u2019t introduce hot carbon fouling into the action, which means less maintenance, longer-lasting performance, and less wear on internal components than you\u2019d get with direct-impingement ARs. <\/p>\n\n\n\n<p>The <a href=\"https:\/\/gunsamerica.com\/digest\/feed-your-garand-what-it-wants-adjustable-gas-plug-install-and-test\/\" target=\"_blank\" class=\"clickTracking\" campaign=\"hk-mr-a4-hk416-performance-for-anyone-shot-show-2025\" title=\"HK MR A4: HK416 Performance For Anyone -- SHOT Show 2025\"  data-wpil-monitor-id=\"2906\">adjustable gas<\/a> regulator allows the operator to dial it in specifically for suppressed or unsuppressed operation, making it a versatile option for a wide range of uses.
