Availability: In Stock
The B5 Systems AKM-1490 AK stock in plum is a purpose-built upgrade for shooters running 5.5mm-pinned AK folding trunnions who want better ergonomics, adjustability, and modularity without swapping out their receiver. This composite-and-steel stock replaces your factory folder while mounting to the same factory pin, giving you a collapsible length-of-pull adjustment, a non-slip cushioned buttpad, and integrated QD/fixed sling mounts—all in a durable American-made package.
If you're building or maintaining an AK in the 5.5mm platform—whether for hunting, sport shooting, or home defense—this stock fills a real gap between bare-bones folders and full proprietary systems. The optic rail cutout lets you co-witness irons or mount optics without permanent modifications, and the adjustable LOP means it'll fit shooters from compact frames to longer arms. The plum finish is both aesthetic and practical, resisting fingerprints and showing less wear than black.
Fitment note: tolerance stacking across AK manufacturers is real. Most installations are straightforward, but some users may need to tune the fit to their specific receiver. That's normal in the AK world and speaks to why you buy from a dealer who understands the platform, not a generic online warehouse.

This stock is designed for AKs with 5.5mm folding trunnions and mounts using the factory pin. Due to tolerance variations across manufacturers, some fitment may be required. If you're unsure whether your AK uses a 5.5mm trunnion, check your manual or reach out before ordering.
Yes. The stock features an optic rail cutout, allowing you to mount optics or co-witness iron sights without permanent receiver modifications.
The stock includes both fixed sling mounts and steel anti-rotational QD (quick-detach) mounts, giving you flexibility in how you set up your sling.
This is a collapsible (not folding) stock. It adjusts length of pull for different shooter builds and gear, but doesn't fold like the factory folder it replaces.
