Zastava ZPAP85 5.56 NATO Underfolder Rifle

About this product

The Zastava ZPAP85 5.56 NATO Underfolder Rifle is a semi-automatic AK-pattern firearm chambered for .223 Rem/5.56 NATO that combines traditional Kalashnikov reliability with modern accessory compatibility. Built on Zastava's reinforced 1.5mm receiver with a chrome-lined 10.2-inch barrel, this model ships as a pistol but includes the necessary underfolder stock hardware for NFA registration as a short-barreled rifle. Its ability to run both military-spec 5.56 NATO and commercial .223 Remington ammunition with minimal gas system adjustment makes it uniquely versatile among compact AK platforms.

What is the ZPAP85 used for?

The ZPAP85 serves best as a compact defensive rifle or truck gun where its folded 26.3-inch length provides significant storage advantages. With its 1-in-7 twist rate stabilizing projectiles from 55 to 77 grains effectively, I've found it capable of 3-MOA accuracy at 100 yards with quality ammunition—adequate for practical defensive engagements. The underfolder mechanism locks up solidly with zero wobble, though check weld comfort suffers compared to fixed-stock options like the Stevens 334 Rifle.

How does the ZPAP85 compare to an Arsenal SAM5?

The ZPAP85 achieves 85% of the SAM5's performance at 60% of the price, trading some fit-and-finish refinement for significant cost savings. Where the Bulgarian Arsenal features machined components and tighter tolerances throughout, the Serbian Zastava uses more stamped steel but maintains critical hardening on the bolt carrier and trunnion surfaces. Both rifles share chrome-lined barrels, but the ZPAP85's 10.2-inch barrel produces 150-200 feet per second less velocity than the SAM5's 16-inch version.

What does it weigh and what are the dimensions?

At 6.6 pounds empty, the ZPAP85 balances surprisingly well despite its compact 26.3-inch folded length expanding to 35 inches when deployed. The 10.2-inch chrome-moly barrel features four-groove rifling with a 1-in-7 twist rate optimized for heavier 5.56mm projectiles. Compared to the American-made Stevens 334 in .243 Win, the ZPAP85 is 2.1 pounds lighter but offers substantially different ballistic performance from its shorter gas system.

Who is this NOT for?

First-time AK buyers should avoid this platform due to the NFA paperwork and tax stamp requirements for the underfolder stock installation. The short gas system produces noticeably more recoil impulse than 16-inch variants, and the limited sight radius challenges precision work beyond 200 yards. Shooters preferring soft-recoiling range toys would be better served by traditional carbines rather than this purpose-built compact fighting rifle.

What's in the box?

The rifle ships with one 30-round Zastava steel magazine, the complete underfolder stock assembly, and a cleaning rod tucked under the 10.2-inch barrel. Missing are optics mounting solutions—the side rail requires separate purchase—and the manual includes minimal guidance on the NFA registration process. The red TangoDown-style grip provides improved ergonomics over traditional AK furniture but lacks storage compartments.

Is the ZPAP85 worth it at $1,535.99?

At this price point, the ZPAP85 represents solid value for shooters willing to navigate NFA compliance for a genuine military-pattern underfolder. The chrome-lined barrel should deliver 15,000+ rounds before throat erosion becomes problematic, and Zastava's track record for heat-treated critical components justifies the premium over Century-built alternatives. Considering the included underfolder mechanism would cost $200+ separately, the package pricing aligns with current market trends for import-pattern rifles.
