It is a 9mm Parabellum open-bolt, semiautomatic, blowback carbine feeding from 20-round magazines. It was tested by the US military at Aberdeen Proving Grounds, and rejected for a number of reasons, including not being in the US standard .45 ACP cartridge and not being full automatic. However, the British were in dire need of small arms, and S&#038;W decided to pursue sales to the UK rather than redesign the gun to US taste.<\/p>\n<p>The UK ordered a large number, but upon putting the first guns through trials found them to be unsatisfactory. The 9x19mm loading used by the British was substantially hotter than what S&#038;W had used in designing the weapon, and receiver endcaps were shearing off in as few as 1000 rounds under British testing. The British cancelled the order, and took delivery of S&#038;W revolvers in lieu of a refund on their (sizable) down payment. At the end of the war, all but 5 of the 1,010 guns delivered were destroyed.<\/p>\n<p>In 1974, crates of leftover Light Rifles were discovered in the basement of S&#038;W &#8211; 137 MkI types and 80 MkII  types. These were sold as a batch to Bill Orr of GT Distributors, who then sold them on the commercial market. Orr also petitioned ATF to exempt the guns from NFA short-barreled rifle classification (the guns have 9.75\u201d barrels), and was successful &#8211; so these transfer as ordinary rifles despite their short barrels.<\/p>\n<p>The difference between the MkI and MkII is the safety and the firing pin. The MkI has a lever safety which locks the bolt in the rearward position, and a floating firing pin with a lever actuator like a Beretta M38. The MkII has a rotary sleeve safety which locks the bolt either forward or rearward (a better system), and a fixed firing pin milled into the bolt face. Note that contrary to most literature, the MkII receiver was not strengthened to alleviate the durability problems found by British testing.<\/p>\n<p>If you enjoy Forgotten Weapons, check out its sister channel, InRangeTV! <a href=\"http:\/\/www.youtube.com\/InRangeTVShow\" target=\"_blank\" rel=\"noopener noreferrer\">http:\/\/www.youtube.com\/InRangeTVShow<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Mark I sold for $10,925 Mark II sold for $10,350 http:\/\/www.patreon.com\/ForgottenWeapons Cool Forgotten Weapons merch! http:\/\/shop.bbtv.com\/collections\/forgotten-weapons Designed in 1939 by S&#038;W engineer Edward Pomeroy, the S&#038;W Light Rifle is an extremely well manufactured but rather poorly thought out carbine.
