HIPERFIRE AK Main Spring Black

Introducing the new XAK mainspring for AK platforms. Our innovative mainspring features tri-twist, music wire construction designed specifically for our XAK series triggers, delivering a consistent 2+ lb pull weight and a robust, positive reset. Compatible with both our XAK line of triggers and other stock and aftermarket AK fire controls, the XAK mainspring ensures enhanced performance and reliability. Please note, pull weight and feel may vary across receivers and trigger assemblies due to the absence of a universal Mil-Spec standard for AK platforms. At Hiperfire, we prioritize transparency, providing accurate pull weight specifications based on our XAK triggers paired with XAK mainsprings. We advise caution when using our products with triggers or mainsprings from other brands, as we cannot guarantee the same pull weight consistency in those configurations.
