However, Finns wouldn\u2019t be Finns, if they didn\u2019t come up with a meticulous testing program.<\/p>\n<p>First, they had to decide which round they would use. There were three options: NATO 7.62\u00d751, Soviet 7.62\u00d739, and developing their own ammunition.<\/p>\n<p>In this case, the Finnish Defense Forces managed to make better decisions compared to bigger and richer countries and decided that creating their own round would not make sense.\u00a0NATO 7.62\u00d751 was considered to be too large and heavy, and it left Finland with 7.62\u00d739.<\/p>\n<div class=\"wp-caption alignnone\" style=\"width: 920px\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.thefirearmblog.com\/blog\/wp-content\/uploads\/2023\/02\/7644626-920x613.jpg\" alt=\"\" width=\"920\" height=\"613\"\/><\/p>\n<p class=\"wp-caption-text\">To this day, 7.62\u00d739 remains the main round used by the Finnish Defense Forces<\/p>\n<\/div>\n<p>Naturally, the designer had to obtain an AK and test it to develop a new weapon of this caliber. It wasn\u2019t an easy task \u2013 in 1956, the first AKs were revealed to the public, and the technology data package was transferred to a few socialist states (if you want to know more, check out my<a href=\"https:\/\/www.thefirearmblog.com\/blog\/2024\/02\/16\/hungarian-aks-country-revealed-aks-world\/\">\u00a0article about Hungarian AKs<\/a>).<\/p>\n<p>In 1956, the Finnish military was looking for a way to buy AKs without much optimism. However, they quickly found a shady Polish dealer who was willing to sell one sample.\u00a0Erkki Maristo, inspector of the Finnish Defense Forces Weapons Department traveled to Poland to obtain that sample.<\/p>\n<p>The rifle was disassembled into parts and shipped by sea through the Polish port of Gdansk to the Finnish port of Kotka. Later on, the Finnish military ordered a batch of Polish-made AKs for additional testing and evaluation through official channels.<\/p>\n<div id=\"attachment_1346190\" class=\"wp-caption alignnone\" style=\"width: 1500px\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-1346190 size-full\" src=\"https:\/\/www.thefirearmblog.com\/blog\/wp-content\/uploads\/2024\/04\/type3.jpg\" alt=\"\" width=\"1500\" height=\"844\" srcset=\"https:\/\/www.thefirearmblog.com\/blog\/wp-content\/uploads\/2024\/04\/type3.jpg 1500w, https:\/\/www.thefirearmblog.com\/blog\/wp-content\/uploads\/2024\/04\/type3-390x219.jpg 390w, https:\/\/www.thefirearmblog.com\/blog\/wp-content\/uploads\/2024\/04\/type3-768x432.jpg 768w, https:\/\/www.thefirearmblog.com\/blog\/wp-content\/uploads\/2024\/04\/type3-660x371.jpg 660w, https:\/\/www.thefirearmblog.com\/blog\/wp-content\/uploads\/2024\/04\/type3-800x450.jpg 800w, https:\/\/www.thefirearmblog.com\/blog\/wp-content\/uploads\/2024\/04\/type3-920x518.jpg 920w\" sizes=\"auto, (max-width: 1500px) 100vw, 1500px\"\/><\/p>\n<p class=\"wp-caption-text\">Author with a pre-production Type 3 AK.

The first was AR-10. Armalite actually developed a special version of the rifle chambered in 7.62\u00d739, but it was late for trials. Another interesting contender was\u00a0SIG 510-3, a rolled-delayed Swiss rifle, also chambered for 7.62\u00d739.<\/p>\n<p>But since both weapons arrived late,\u00a0Lauri Oksanen had more time to perfect his prototype before the trials began. Even at this stage, he tried to minimize the use of wood, trying to make the rifle cheaper in future mass production.<\/p>\n<p>Trials started on June 23, 1958, and lasted until July 5, when three weapons participated: M58, Polish AK, and Swiss SIG 510-3. Tests included water, mud, and freezing the rifle. Captain Mauri Makela was in charge of the trials.<\/p>\n<p>M58 had the best overall results but experienced some problems with a trigger mechanism, which malfunctioned and occasionally fired two-shot bursts in semi-auto mode.<\/p>\n<div class=\"wp-caption alignnone\" style=\"width: 920px\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.thefirearmblog.com\/blog\/wp-content\/uploads\/2022\/06\/RK62_4-920x518.jpg\" alt=\"\" width=\"920\" height=\"518\"\/><\/p>\n<p class=\"wp-caption-text\">To this day, Finnish Defense Forces are using some of the early production RK 62s<\/p>\n<\/div>\n<p>But most importantly, these tests convinced defense forces that the new weapon of the Finnish army could indeed be manufactured domestically and there was no need to buy a weapon from abroad.<\/p>\n<p>In Part 2 of this article, I will talk about the beginning of mass production of RK 62 and how its design withstood the test of time.<\/p>\n<hr\/>\n<p><em>The author would like to thank the Finnish company Valman Ltd for contributing to the research and photos used in this article. <a href=\"https:\/\/www.instagram.com\/valman_ltd\/\">VALMAN<\/a> is a company that designs and manufactures upgrades for the AK platform, including items designed specifically for RK 62.<\/em><\/p>\n<\/p><\/div>\n<p><script async defer src=\"https:\/\/platform.instagram.com\/en_US\/embeds.js\"><\/script><br \/>\n<br \/><br \/>\n<br \/><a href=\"https:\/\/www.thefirearmblog.com\/blog\/2024\/04\/17\/aks-finland-part-1-development-history\/?utm_source=rss&#038;utm_medium=rss&#038;utm_campaign=rss\">Source link <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The small European country of Finland always had a great reputation when it comes to arms production.
