Description
The B5 Systems AK Stock Fixed in Plum is a straightforward upgrade that improves how your AKM handles without overcomplicating things. Built here in the USA from composite materials with steel reinforcement, this stock is designed to be durable and reliable for real shooting. It drops right in as a replacement for the factory fixed stock on standard AKM-pattern stamped receivers, though you may need to do minor fitment adjustments depending on your specific receiver tolerances.
Adjustable Fit for Your Shooting Style
The length of pull adjusts through five distinct positions from fully collapsed to fully extended, so you can dial it in for your body type, gear, or shooting stance. The adjustment button is easy to access and locks positively into place so you don't have to worry about it shifting during firing. The cushioned buttpad is designed to absorb recoil and give you a solid shoulder weld, which adds to stability and comfort during extended shooting sessions.
Sling Mounting and Rail Options
You get both fixed sling mounts and steel anti-rotational QD mounts built in, giving you flexibility in how you carry and use the rifle. The stock also includes an optic rail cutout if you want to add sight systems or accessories. This combination keeps things simple while giving you options for customization.
The whole package weighs just over 10 ounces and measures 9.5 inches long, so it doesn't add unnecessary bulk to your rifle. For anyone looking to make an AK more shootable and comfortable without chasing complicated features or expensive alternatives, this fixed stock delivers practical upgrades that you'll notice in the field.

Frequently Asked Questions
Will this fixed stock fit my AK?
The B5 AK Stock Fixed is designed for standard AKM-pattern stamped receivers. Due to manufacturing tolerances across different makers, you may need to do minor fitment adjustments. If you have a folding trunnion receiver, you'll need one of B5's folding models (4.5mm or 5.5mm pin versions) instead. Always verify your receiver type before purchasing.
How does the adjustable length of pull work on the fixed stock?
The stock features a button at the bottom that lets you adjust between five different positions. Each position locks in securely so there's no movement during shooting. You can go from fully collapsed to fully extended depending on your fit preferences, and the button is easy to grab and manipulate even while holding the rifle.
Is the installation complicated?
Installation is straightforward but involves a couple extra steps compared to some stocks. You'll remove the old stock, install the stock connector piece to your receiver, then attach the buttstock itself. B5 Systems provides clear instructions, and the whole process is manageable if you're comfortable with basic gun work. If you've done AK furniture swaps before, you'll find this familiar.
Can I use both traditional slings and QD slings with this stock?
Yes. The stock has fixed sling mounts for traditional slings and steel anti-rotational QD mounts so you can use quick detach slings. This gives you flexibility to set up the rifle however you prefer without needing to buy different hardware.
