The Marlin XT Series is a versatile line of bolt-action rimfire rifles designed for target practice and small game hunting. Introduced in 2011, the XT Series includes models chambered in both .17 HMR and .22 LR calibers, catering to various shooting preferences. These rifles feature Marlin's patented Micro-Groove rifling, which enhances accuracy by reducing bullet deformation as it travels down the barrel. The Pro-Fire Adjustable Trigger provides a crisp, customizable trigger pull, similar to the Savage AccuTrigger, enhancing the shooter's control and overall shooting experience. Key models in the XT Series include the XT-22, which is chambered for .22 Long Rifle and features a 22" blued sporter barrel, adjustable iron sights, and a walnut-finished hardwood Monte Carlo comb stock. For youth shooters, the XT-22YR offers a shortened 16.25" barrel and a reduced length of pull. The XT-22M variant, designed for .22 WMR, offers similar features with a blued sporter barrel and either a 4-shot or 7-shot box magazine. In the .17 HMR lineup, the XT-17V features a heavy varminter barrel and a walnut-finished stock, while the XT-17VSLB offers a stainless steel barrel with a gray laminate thumbhole stock, providing enhanced stability and comfort. The XT Series rifles are designed with versatility and customization in mind, making them an excellent choice for both novice and experienced shooters​
