B5 Systems Akm-1494 Ak Stock 4.5Mm Odg

The B5 Systems AK stock in OD Green is a US-made replacement for tired factory folder setups on Kalashnikov platforms. If your AK has a standard 4.5mm folding trunnion, this collapsible stock drops in via the factory pin—no permanent modifications needed. B5 engineered it to feel more like a modern rifle than a surplus gun: you get a cushioned buttpad that actually softens recoil, sling mounting options for both fixed and quick-detach rigs, and length-of-pull adjustment so shorter and taller shooters can get behind the gun comfortably. There's even a rail cutout for mounting glass, a practical touch on a platform where optics aren't always straightforward.

Built from composite materials with steel hardware and assembled in the USA, this stock is tough enough for hunting, range work, or tactical training without adding heft—it weighs just 12.5 ounces. The collapsible design keeps your AK maneuverable in vehicles, tight spaces, or wherever a shorter profile matters. The nonslip buttpad is a small detail that makes a real difference in rough conditions or when you're wearing light clothing.

One real-world note: AK tolerances vary widely depending on the rifle's country of origin and age. B5 designed this for the 4.5mm pin standard, but you may need to do a little fitting to get a perfect lock-up—that's AK life. Once it's seated, it's solid. The OD Green finish blends with modern tactical gear or hunting setups, and the quality hardware won't rattle loose over years of use.

Frequently Asked Questions

Will this B5 AK stock fit my rifle?

It mounts via the standard 4.5mm folding trunnion pin. Because AK manufacturing tolerances vary significantly across countries and manufacturers, some fitment work may be required to achieve a tight lockup. If you're unsure whether your rifle has the right trunnion type, bring the rifle or measure the pin diameter before ordering.

Can I adjust the length of pull on this stock?

Yes. The stock features collapsible, adjustable length of pull so you can dial in the right measurement for your arms and shooting style, and it collapses for closer-quarters handling or vehicle storage.

What sling mounts are included?

The stock comes with fixed sling mounts and steel anti-rotational quick-detach (QD) mounts, giving you flexibility in how you attach a sling for hunting, tactical training, or range use.

Can I mount an optic on this stock?

Yes. There's an optic rail cutout designed to accommodate modern sight systems, making it easier to run glass on your AK without having to improvise mounting solutions.
