TL;DR
- Gunsmith Part 4 now requires silenced OP-SKS with specific stats instead of M4
- OP-SKS is cheaper than regular SKS due to built-in dovetail mount for scopes
- Tapco parts and PSO-1 scope available from Level 1 traders
- Silencer is the hardest component – use Flea Market or Scav runs
- Complete build costs approximately 50,000-80,000 roubles depending on silencer luck
Games and Esports Articles
The recent Escape from Tarkov 0.13 update completely overhauled the Gunsmith Part 4 quest, replacing the previous M4 assembly requirement with a silenced SKS/OP-SKS build. This change significantly impacts early-game progression strategies, as the new configuration demands different trader relationships and loot priorities.
To successfully complete this quest, your customized weapon must meet these exact specifications:
- Minimum 60 durability points
- 35 or higher ergonomics rating
- Total recoil sum not exceeding 350
- Equipped with any compatible scope
- 20-round magazine capacity or greater
- Fully suppressed with appropriate silencer
Common Mistake: Many players attempt to use the standard SKS, failing to realize it lacks the dovetail mount necessary for scope attachment without expensive additional components.
Strategic weapon selection is crucial for budget-conscious operators. The OP-SKS variant provides significant cost advantages because its integrated dovetail mount directly accepts PSO-series scopes, eliminating the need for expensive rail systems. You can purchase the base rifle directly from Jaeger immediately upon unlocking him at Level 1.
The essential Tapco modernization kit components present multiple acquisition pathways. Mechanic offers these parts at Level 1, while Peacekeeper supplies the required 20-round magazine. For maximum economy, consider the barter trade option: exchange one GP coin plus a standard screwdriver with Mechanic for a complete pre-modified OP-SKS.
Pro Tip: Always check your scavenger loadout between raids, as they occasionally spawn with suppressed SKS configurations that can be extracted for quest completion.
Trader level requirements are deliberately minimal for this quest. Prapor sells the PSO-1 scope at Level 1, and any variant will satisfy the optical requirement. This accessibility makes the Gunsmith Part 4 achievable relatively early in your Tarkov career progression.
Begin the modification process by carefully removing the original wooden stock and standard magazine from your OP-SKS. The Tapco synthetic stock system provides improved ergonomics and recoil control while being significantly lighter than traditional wood components.
Installation follows a logical sequence: first attach the Tapco stock assembly, then mount the PSO-1 scope directly to the integrated dovetail rail. The 20-round magazine slots into place after the stock modification is complete. This specific order prevents interference between components during assembly.
Assembly Insight: The PSO-1 scope’s zeroing mechanism works optimally with 7.62x39mm ammunition, providing accurate shot placement at various engagement distances common in Tarkov’s combat environments.
Final configuration verification should include checking that all attachment points are secure and the weapon meets the precise stat requirements before attempting quest turn-in.
The weapon suppressor represents the most challenging component to source economically. Early-level traders don’t stock SKS-specific silencers, forcing operators to pursue alternative acquisition methods.
The Flea Market typically offers multiple suppressor options, though prices fluctuate based on trader resets and player demand cycles. Monitor market trends and purchase during price dips if possible.
Your scavenger runs provide another viable pathway. Scav characters periodically spawn with pre-suppressed SKS variants – systematically checking these loadouts can yield the required component without financial investment.
Advanced Strategy: While adapter kits exist that enable SKS platforms to accept AK-pattern silencers, these typically become available later in trader progression, making them less practical for early quest completion timelines.
