Description
There are plenty of underfolder AKs floating around, but very few built like this one. The Arsenal SAM7UF-85 starts with a receiver that is hot-die hammer forged, then milled from that forging over several hours of machine time. That process squeezes out the internal voids you can get with cast or bar-stock receivers and leaves you with dense, fine-grained steel that shrugs off round counts most rifles never see. The bolt, carrier, and trigger group get the same forged treatment, and the 16.25 inch barrel is hammer forged and chrome lined for long service life and easy cleanup after corrosive-primed surplus ammo.
A Smarter Underfolding Stock on the SAM7UF
Old-school underfolders have a reputation for being a little wobbly, and Arsenal clearly took that personally. The SAM7UF uses a modern straight-back underfolding buttstock with reinforced arms that locks into both sides of the receiver with four solid pins, whether it's folded or extended. The result is a noticeably tighter lockup that keeps the sights steady and helps manage muzzle climb, while still folding down for compact storage or transport. Black polymer furniture with a stainless steel heat shield in the lower handguard rounds out the package, so extended range sessions won't cook your support hand.
SAM7UF-85 Details That Matter at the Range
The -85 designation means this one ships with the enhanced fire control group, which gives you a smoother, more refined pull than a standard AK trigger. You also get 14x1mm left-hand muzzle threads under a removable muzzle nut, a bayonet and accessory lug, a left-side scope rail for mounting optics, and an 800 meter adjustable rear sight. It feeds from a 10-round mil-spec Bulgarian magazine and accepts standard AK mags, so building out your loadout is simple.
Why the Arsenal SAM7UF Earns Its Reputation
Milled Bulgarian underfolders in this condition used to be the stuff of import wish lists. The SAM7UF-85 brings that classic silhouette back with modern manufacturing and fit and finish that stands out the second you pick it up. If you've been waiting on a milled AK worth handing down, this is the one to grab.

Frequently Asked Questions
Does the Arsenal SAM7UF-85 accept standard AK magazines?
Yes. It ships with one 10-round mil-spec Bulgarian Arsenal magazine, and it runs standard mil-spec AK-47 pattern 7.62×39 magazines, including Arsenal's Circle 10 mags. If you want higher capacity for range days, standard 30-rounders drop right in.
Is the underfolding stock on the SAM7UF-85 wobbly like older underfolders?
No, and that's one of the main selling points of this rifle. Arsenal designed a modern straight-back underfolder with reinforced arms that locks into both sides of the receiver with four solid pins, both folded and extended. The lockup is far tighter than the loose, rattly underfolders many people remember, and it helps keep the rifle stable under recoil.
Can I mount an optic on the Arsenal SAM7UF?
Yes. The rifle includes a left-side AK scope rail on the receiver, so any standard AK side-mount optic setup will work. Just keep in mind that if you fold the stock, some larger side mounts can interfere, so pick your mount with the underfolder design in mind.
What does the -85 mean on the SAM7UF-85?
The -85 designation indicates this version comes with the enhanced fire control group, which delivers a smoother, cleaner trigger pull than a standard AK trigger. Everything else follows the SAM7UF formula: milled and forged receiver, chrome-lined hammer-forged barrel, and the reinforced underfolding stock.
