Description
The B5 Systems AK Stock Fixed brings a solid upgrade to AKM-pattern rifles that roll out with basic factory stocks. This isn't just a cosmetic swap either. It features a collapsible length-of-pull adjustment so you can dial in the perfect fit, which makes a real difference in how a rifle handles and how naturally you shoulder it.
Ergonomics and Comfort Built Into the Design
The stock sits solidly on the shooter's shoulder thanks to its cushioned, non-slip buttpad. That padding isn't just for comfort, it helps absorb recoil and gives you a consistent shouldering experience. The composite construction keeps things lightweight at 10.5 ounces while staying durable enough for real use. An integrated optic rail cutout means you can mount optics without any interference, which is handy if your rifle setup includes modern sighting systems.
Versatile Attachment Options
Sling attachment gets multiple options here. Fixed sling mounts and steel anti-rotational QD mounts mean you can run whichever attachment method you prefer. The steel QD mounts won't strip or wear out, which matters if your rifle sees regular use. Everything mounts directly to the standard AKM factory trunnion, making this a genuine drop-in upgrade.
Solid Construction Made Stateside
B5 Systems builds these in the USA using durable composite material paired with steel hardware. The overall dimensions are 9.5 inches long by 1.2 inches wide by 4.33 inches high. Standard AKM pattern stamped receivers should fit without issue, though minor fitment adjustments are possible due to manufacturer tolerance variations.

Frequently Asked Questions
Will the B5 Systems AK Stock Fixed work with my rifle?
This stock fits standard AKM pattern stamped receivers. Due to manufacturer tolerance variations, minor fitment adjustments may occasionally be needed. If your rifle uses a standard AKM trunnion, you should be good to go.
Can I adjust the length of pull on this fixed stock?
Yes. Despite being called a fixed stock, it features a collapsible length-of-pull adjustment. This lets you dial in the perfect fit without permanently fixing the length, which is useful if different shooters use the rifle or if you wear different gear.
What sling attachment options does the AK Stock Fixed offer?
You get both fixed and QD sling mounts with this stock. The QD mounts are steel with anti-rotation hardware, so they're built to handle repeated attachment and detachment without wearing out. You can use whichever attachment method works best for your setup.
Is the cushioned buttpad going to wear out or degrade?
The non-slip buttpad is built into the stock and designed for durability, but like any cushioned component, it will eventually wear with extensive use. The composite material and steel hardware are constructed to last through demanding use, and the overall design prioritizes longevity.
