The OP-SKS Modification: A Closer Look 

1. Achieving Required Durability and Ergonomics 

In Escape from Tarkov, modifying the OP-SKS to meet the Gunsmith Part 4 quest requirements necessitates careful selection of parts and attachments. The primary benchmarks include achieving a durability of ≥60 and ergonomics of ≥35. Here are the recommended components to meet these specifications: 

Recommended Parts for Durability and Ergonomics 

• TAPCO Intrafuse Chassis: This is a pivotal component that significantly enhances the ergonomics of the OP-SKS by providing a more modernized platform for additional attachments. Available from Skier at loyalty level 2 or on the flea market. 

• TAPCO Saw Style Pistol Grip: Designed to be attached to the TAPCO Intrafuse Chassis, this grip further boosts the ergonomics rating. Available from Skier at loyalty level 2 or on the flea market. 

• UTG SOCOM Rail Mount: Essential for mounting optics, this rail system contributes to the overall ergonomics by allowing for better sight picture options. Can be acquired through barter trades with Skier or found on the flea market. 

• Bastion Dust Cover: Replacing the standard dust cover with Bastion adds to both durability and ergonomics. It also provides a stable platform for mounting scopes. Obtainable from Mechanic at loyalty level 1 or via barter trades. 

Additional Modifications 

• Suppressors: While one suppressor is sufficient, choosing a high-quality suppressor like the Hexagon SKS suppressor can reduce noise without compromising durability. 

• Scopes: Opting for lightweight scopes such as PSO-1 or Valday PK-120 ensures meeting sighting range requirements while keeping weight manageable. 

Example Build for Durability and Ergonomics Optimization 

To illustrate, consider this example build that meets all required specifications: 

• Base Weapon: OP-SKS 

• Chassis: TAPCO Intrafuse 

• Grip: TAPCO Saw Style Pistol Grip 

• Rail Mount: UTG SOCOM Rail Mount 

• Dust Cover: Bastion 

• Suppressor: Hexagon SKS suppressor 

• Scope: PSO-1 

This setup achieves: 

Durability: Significantly above ≥60 due to high-quality parts. Ergonomics: Well over ≥35 thanks to ergonomic enhancements from TAPCO components. 

By focusing on these key parts and modifications, players can effectively meet the durability and ergonomics requirements laid out in Gunsmith Part 4. 

2. Managing Recoil Effectively and Maximizing Sighting Range 

Recoil Management Techniques: 

• Use of Muzzle Devices: Installing a suppressor or compensator can significantly reduce recoil. For the OP-SKS, options like the Hexagon SKS Suppressor or TAPCO Intrafuse Compensator are popular choices. 

• Stock Adjustments: Opting for stocks with better recoil properties like the TAPCO Intrafuse Stock helps in managing recoil more effectively. 

• Foregrips and Bipods: These attachments offer additional stability and control, making it easier to manage the gun’s recoil during continuous firing. 

Optimal Scopes for Sighting Range: 

• PSO-1M2-1 Scope: Provides excellent magnification and clarity, meeting the sighting range requirement of ≥600m. 

• Valday PS-320 1/6x Scope: Versatile option with variable magnification suitable for both close-range and long-range engagements. 

Balancing these components ensures that your OP-SKS build meets the specified Recoil ≤350 and Sighting range ≥600m criteria, essential for completing the quest successfully. 

3. Strategies for Weight Management and Magazine Capacity Optimization 

OP-SKS modification requirements dictate that players must meet specific criteria, including Weight ≤6kg and Magazine capacity ≥20 rounds. These specifications are crucial to achieving a successful build. 

Weight Management Strategies 

Maintaining the weight of your OP-SKS build under 6kg without compromising performance involves selecting lightweight yet durable components. Key strategies include: 

• Using the TAPCO Intrafuse Chassis: This chassis is not only lightweight but also offers enhanced ergonomics. 

• Opting for Compact Scopes: Choose scopes that provide the required sighting range without adding unnecessary weight. 

• Minimalist Attachments: Avoid overloading the rifle with heavy attachments; prioritize essential modifications that meet the requirements. 

20 Round Magazine Acquisition 

To meet the magazine capacity requirement, you need a magazine with at least 20 rounds. The necessary magazine can be found through: 

• Mechanic Level 2: Once you reach level 2 loyalty with Mechanic, you can purchase the ProMag Archangel OPFOR SKS 20-round magazine. 

• Flea Market: The flea market often has these magazines available for purchase from other players, potentially at competitive prices. 

Ensuring your OP-SKS meets these detailed specifications—Durability ≥60, Ergonomics ≥35, Recoil ≤350, Sighting range ≥600m, Weight ≤6kg, and Magazine capacity ≥20 rounds—is essential for completing the quest efficiently. Each specification plays a critical role in balancing performance and compliance with the quest’s demands.
