We&#8217;ve kept the best and improved the rest by creating a system that combines all of the operational reliability that you know and trust, with the modern elements that serious shooters demand.<\/p>\n<p>This limited edition, custom shop model is hand crafted to exacting standards and is constructed with a milled receiver, all machined parts, hammer forged chrome lined barrel, and aircraft-grade aluminum handguard. Chambered in 7.62x39mm it is available in SBR, with pistol and rifle configurations coming soon.<\/p>\n<h4>THE ULTIMATE IN FLEXIBILITY<\/h4>\n<p>The AK-20 is designed with a proprietary integrated adjustable gas system that allows you to easily toggle between ammunition types and firing options depending on shooting conditions. You can choose between standard or sub-sonic ammunition, and depending on the model, switch to manual action for quieter shooting or suppressed gas operation with less muzzle flash and minimized recoil.<\/p>\n<p>The 3-position tunable AK-20 gas system works in the following way:<\/p>\n<ol>\n<li>Turn to the right &#8220;MIL-STD&#8221; for use with standard ammunition.<\/li>\n<li>Turn to the left &#8220;SUB&#8221; for subsonic ammunition when suppressed.<\/li>\n<li>Center setting has no marking and restricts gas flow.\n<ol type=\"a\">\n<li>Subsonic ammunition suppressed &#8211; restricts gas flow and requires shooter to manually cycle rounds.<\/li>\n<li>Supersonic ammunition suppressed &#8211; restricts gas flow to soften the bolt cycling.<\/li>\n<\/ol>\n<\/li>\n<\/ol>\n<h4>OPTIMAL ACCURACY<\/h4>\n<p>Another key feature of the AK-20 is the newly configured handguard, barrel, and gas tube. Unlike traditional models, this design minimizes contact between the parts allowing them to work independently for greater heat resistance, overall stability, and highly improved accuracy.<\/p>\n<h2>Arsenal Suppressor Ready (ASR)<\/h2>\n<p>Inspected to verify exceptional bore-to-thread alignment for suppressor applications. As part of the ASR qualification process, rifles are tested with select suppressors from leading manufacturers to verify proper concentricity and coaxial alignment. Because suppressor and mounting system designs and dimensions vary between manufacturers, compatibility with any specific suppressor is not guaranteed, and users should verify proper fit and alignment prior to installation and use.<\/p>\n<h4>FEATURES<\/h4>\n<ul>\n<li>Factory SBR NFA item with U.S. manufactured milled receiver.<\/li>\n<li>Free Floating 8.5&#8243; hammer forged chrome lined barrel with 24&#215;1.5mm right-hand threads.<\/li>\n<li>KR-009B 4-piece flash hider.<\/li>\n<li>Includes 30 round Mil-Spec double stack M-47W magazine.<\/li>\n<li>3-position gas system (Standard\/Subsonic\/Manual).<\/li>\n<li>High quality free floating Picatinny top rail that extends over the length of the receiver for added stability and streamlined optics mounting. 10.2 inches long with 25 mounting slots.<\/li>\n<li>Aluminum stock with adjustable cheek rest and QB points.<\/li>\n<li>MagPul M-LOK\u00ae lower handguard.<\/li>\n<li>QD ports built into the right and left rear of the receiver.<\/li>\n<li>High-quality MIL-SPEC black Cerakote metal coating for enhanced appearance plus wear, corrosion and chemical resistance.<\/li>\n<li>&#8220;ASR&#8221; Arsenal Suppressor Ready.<\/li>\n<\/ul>\n<h2>SPECIFICATIONS<\/h2>\n<table class=\"specs\" width=\"342\">\n<tbody>\n<tr>\n<td>SKU<\/td>\n<td>SASM7K-29<\/td>\n<\/tr>\n<tr>\n<td>Model<\/td>\n<td>SASM7K<\/td>\n<\/tr>\n<tr>\n<td>UPC<\/td>\n<td>810054135340<\/td>\n<\/tr>\n<tr>\n<td>Caliber<\/td>\n<td>7.62&#215;39 mm<\/td>\n<\/tr>\n<tr>\n<td>Total length<\/td>\n<td><\/td>\n<\/tr>\n<tr>\n<td>Barrel length<\/td>\n<td>215 mm (8.5 in.)<\/td>\n<\/tr>\n<tr>\n<td>Rifling<\/td>\n<td>4 grooves<\/td>\n<\/tr>\n<tr>\n<td>Twist rate<\/td>\n<td>1 in 240 mm (9.44 in.)<\/td>\n<\/tr>\n<tr>\n<td>Weight w\/o magazine<\/td>\n<td><\/td>\n<\/tr>\n<tr>\n<td>Muzzle velocity<\/td>\n<td>600 m\/s (1,969 fps)<\/td>\n<\/tr>\n<tr>\n<td>Effective range<\/td>\n<td>300 m (328 yds)<\/td>\n<\/tr>\n<tr>\n<td>Maximum range<\/td>\n<td>1,100 m (1,203 yds)<\/td>\n<\/tr>\n<tr>\n<td>Rate of fire<\/td>\n<td>40 rds\/min (practical)<\/td>\n<\/tr>\n<tr>\n<td>Rear sight range<\/td>\n<td>not shipped with iron sights<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"excerpt":{"rendered":"<p>Arsenal AK-20 SASM7K SBR 7.62x39mm 8.5&#8243; Barrel with Gas Adjuster, Picatinny Top Rail, Aluminum Hand Guard,\u00a0aluminum stock with adjustable cheek rest and QB points, KR-009B 4-piece flash hider, and 30rd magazine.<\/p>\n","protected":false},"featured_media":19674,"comment_status":"open","ping_status":"closed","template":"","meta":{"_monsterinsights_skip_tracking":false},"product_brand":[],"product_cat":[240,184],"product_tag":[],"class_list":["post-19673","product","type-product","status-publish","has-post-thumbnail","product_cat-ak20","product_cat-sbr","first","instock","taxable","shipping-taxable","product-type-simple"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.8 -
