ZPAP Break-In Guide: What Matters, What Doesn’t

You bought a ZPAP because you want a rifle that runs hard and keeps its cool. Zastava gives you that with a stout 1.5 mm receiver, a bulged trunnion, and a simple long-stroke system that rewards basic care with long term reliability.

So let’s talk about ZPAP break-in the practical way: what actually helps your rifle settle in, what you can skip, and how to start strong, making your first range trip a success.

Start With A Simple Definition Of “Break-In”

For ZPAP break-in, you do not need mystery rituals or secret handshakes. You need three things:

1. Confirm safe function
2. Add smart lubrication at friction points
3. Run a few range sessions with good habits

That’s it. Your goal equals smooth operation, consistent lockup, and a routine you can repeat.

The First-Day Checklist Before You Fire A Round

A clean start helps every ZPAP break-in plan.

1. Confirm the rifle stays unloaded while you check it.
   Zastava’s manual lays out a clear unload and chamber-check process before you do anything else. Follow it every time, even at home.
2. Inspect ammo.
   Use the correct caliber and skip damaged rounds. The manual warns against dirty, wet, corroded, bent, or damaged cartridges, since they can cause serious problems.
   This step matters more than any “break-in” myth.
3. Remove factory oils and shipping grime.
   Plan a quick field strip and wipe major contact surfaces. You do not need a deep tear-down. Zastava’s own post-range routine shows a fast strip that exposes the parts that collect most fouling: bore, chamber, gas piston, gas tube, bolt face, extractor area, rails, and the fire-control zone.
4. Choose a consistent cleaner/lube.
   Pick one product and stick with it. Zastava Arms offers DRNCH, which they position as a cleaner plus lubricant for regular maintenance.
   Consistency beats “magic sauce” changes every weekend.

The First 200 Rounds: A Practical ZPAP Break-In Plan

Here’s a simple structure for ZPAP break-in:

Phase 1: 60 rounds (function + feel)

• Load known-good magazines.
• Fire slow strings.
• Confirm the rifle feeds, extracts, and goes back into battery.
• Watch ejection pattern consistency, direction, and distance.

Phase 2: 120 rounds (heat + consistency)

• Fire quicker strings with minimal breaking to allow the rifle to heat up.
• Keep a close eye on the firearm’s action to spot any malfunctions.

Phase 3: 20 rounds (confidence check)

• End by alternating between slow strings and short bursts.
• Note the spent casings. Inspect for the firing pin mark on the primer, the extractor mark on the rim, and the ejector mark on the case head.

This approach keeps ZPAP break-in focused on outcomes: reliable cycling and repeatable accuracy.

Lubrication Points That Actually Matter

A good ZPAP break-in routine uses a thin film of lube, not a puddle.

Zastava’s own post-range routine calls out key spots:

• Carrier rails and cam tracks: wipe clean, then add a thin layer of lubricant
• Bolt face and extractor groove: keep carbon out so extraction stays consistent
• Gas piston and tube: wipe and brush as needed, no overthinking

You want a light sheen, not a slip-and-slide.

What Doesn’t Matter Much (So You Can Save Time And Ammo)

A lot of “break-in advice” tries to sell you anxiety. For ZPAP break-in, you can keep life simple:

1. You do not need single-round loading rituals.
   Your rifle needs normal cycling with safe, correct ammo. The manual focuses on correct caliber and safe ammunition handling, not strange round-by-round ceremonies.
2. You do not need abrasive polishing tools.
   Zastava’s rifles are meticulously inspected and will not require any additional hand fitting to get the firearm to function reliably.
3. You do not need to chase “perfectly clean” after every magazine.
   A consistent post-range routine does the job. The chrome-lined barrel also helps resist corrosion and reduces how much fouling clings to the bore surface.

That’s the real “what doesn’t” part of ZPAP break-in: skip the drama, keep the reps.

Cold Weather Notes For ZPAP Owners

If you run your ZPAP in real cold, keep lubrication light and choose products that suit low temps. One Zastava manual notes that below 0°C (32°F) you should avoid lubrication oil and use a dry lubricant sparingly.

That tip helps your ZPAP break-in stay smooth when winter tries to turn everything into syrup.

Build Skill Alongside The Rifle

A rifle can “settle in,” but your hands matter more. Pair your ZPAP break-in with simple at-home practice so your first range trips produce progress, not just noise.

Wrap-Up: The ZPAP Break-In Formula That Works

ZPAP break-in works best when you keep it human:

• Start clean, start safe, use correct ammo
• Lube friction points with a light hand
• Observe the function of your firearm and verify that it cycles properly
• Clean after range days with a repeatable routine

Do that, and your ZPAP will feel smoother each trip—because you built habits that match how Zastava designed the platform.
