The B5 Systems AK stock is a modern, American-made replacement for your factory 5.5mm folding stock that transforms the ergonomics and handling of your rifle. Built from durable composite and steel, this drop-in upgrade mounts directly to your rifle's factory folding trunnion via the 4.5mm pin—no permanent modifications needed. If you're running an AK with a standard 5.5mm folding trunnion and want a more comfortable, feature-rich platform that doesn't compromise modularity, this is a straightforward upgrade that actually gets used in the field.
The stock's collapsible design lets you dial in the length of pull across five positions, so you can optimize it for different shooting positions, body armor, or just dial it in for your natural mount. The cushioned, nonslip buttpad absorbs recoil and keeps things stable when you're shouldering the rifle in less-than-ideal conditions. You get fixed sling mounts and steel QD mounts with anti-rotational design, so your sling or QD attachment stays put and doesn't twist under use—a detail that matters when you need reliability.
One practical touch: the optic rail cutout on top means you're not limited by a folding stock if you want to run optics. Made in the USA from composite materials and steel hardware, the B5 is built to handle real use without the weight penalty of older surplus stocks. Note that fitment can vary depending on your rifle manufacturer's tolerances, but installation is straightforward for anyone comfortable with basic rifle work.
