Description
The FAB Defense UAS-AKP is one of those upgrades that quietly fixes a few things at once. It replaces your fixed AK stock with a left-folding design that trims the overall length way down for storage, transport, or tucking into a shorter case, then locks back open with a solid claw when you pull it out. The main body is MIL-SPEC polymer composite, so it holds up to real field use without piling weight onto the rifle. Installation is straightforward on stamped receivers and comes down to a single bolt with a threaded brass sleeve, though getting the original stock off can take some patience depending on how it was fitted from the factory.
What the UAS-AKP Cheek Riser Actually Does
The standout feature here is the embedded, height-adjustable cheek riser. It pops up at the push of a button to put your eye right behind an optic, then drops flush in a second if you need to go back to iron sights. No permanent risers, no foam pads that deform the stock, no fumbling in the field. That flexibility is why a lot of AK owners running both irons and glass gravitate toward this one. Worth knowing: with the stock folded, you can still fire with the cheek riser in the lower two positions, but the higher settings will contact the charging handle and need to be dropped first.
Built Around Real AK Handling
The UAS-AKP ships as a left-folder by default and the joint is ambidextrous, so it can be configured to fold left or right to suit how you shoot. Quick-detach sling swivel points are built into both sides, and the textured rubber butt pad grips your shoulder or body armor while soaking up some of that 7.62 push. Trigger access stays open even when the stock is folded, which keeps the rifle usable in tight quarters.
This one is made for stamped-receiver AK-47 and AK-74 pattern rifles. If you're running a milled receiver or an underfolder, FAB makes dedicated versions for those, so match the stock to your receiver before ordering.

Frequently Asked Questions
Will the UAS-AKP fit my AK?
This version is designed for stamped-receiver AK-47 and AK-74 pattern rifles. It will not fit milled receivers, underfolders, or Yugo-pattern guns, which use different FAB Defense stocks. Some rifles like certain Century models may need light fitting during install, so it's smart to confirm your receiver type before ordering.
Can I still use my iron sights with the cheek rest?
Yes. The cheek riser drops flush at the push of a button so you can get a proper cheek weld on iron sights, then pops back up to line your eye up behind an optic. That quick swap between the two is one of the biggest reasons people pick this stock.
Which direction does the stock fold?
It ships set up to fold to the left by default. The joint is ambidextrous, so it can be configured to fold left or right depending on your preference and how you run the rifle.
Can I fire the rifle with the stock folded?
You can, with a caveat. Trigger access stays open when folded, and you can fire with the cheek riser in its two lower positions. In the higher riser settings it will contact the charging handle, so drop it down first before firing folded.
