Take your sniper rifle to the next level with the Silverback Airsoft M160 APS 13mm Type Spring for SRS Pull Bolt Version (110 Newton)—a high-tension, precision-engineered spring made specifically for long-range, high-performance airsoft sniping. Whether you're looking to upgrade your Silverback Desert Tech SRS-A1 or another compatible APS-type platform, this spring delivers the power, consistency, and durability required for serious precision shooting.

Built for power and engineered with top-tier materials, this M160-rated spring is a must-have for experienced airsoft snipers who demand maximum range, stable FPS, and field-ready performance.

Precision Fit for the Silverback SRS Pull Bolt System

This spring is specifically designed to work seamlessly with the Desert Tech SRS-A1 sniper rifle, Silverback’s flagship bolt-action platform. With an outer diameter of 13mm and an inner diameter of 11mm, it follows the APS large-type format, making it a perfect drop-in upgrade for a wide range of bolt-action sniper rifles that use this size standard.

In addition to the SRS-A1, the spring is compatible with:

• APS-2

• APS-T96

• APS-SR2

• M24 variants

The tight tolerances and proper spring dimensions ensure a smooth fit with no unwanted play, while the high-quality steel construction offers both durability and consistent output over thousands of shots.

High Power Performance (M160 / 110 Newton)

Rated at M160 (110 Newtons), this spring provides hard-hitting muzzle velocities—ideal for long-range field play. Depending on your rifle’s barrel length, expect the following approximate FPS results when using 0.20g BBs:

• 16" / 420mm Barrel: ~453 FPS

• 22" / 578mm Barrel: ~523 FPS

• 26" / 680mm Barrel: ~529 FPS

This level of power makes the M160 spring ideal for DMR and sniper builds in open outdoor fields. Be sure to check your field’s FPS limits, as the spring may push your rifle beyond standard engagement thresholds. For best results, pair it with upgraded internals, such as a reinforced piston, guide rod, and sear system.

Built for Consistency and Longevity

Silverback’s M160 spring is constructed from high-tensile spring steel, offering excellent resistance to compression fatigue. The consistent coil spacing and polished finish help reduce internal friction, making bolt pulls smoother and more manageable despite the high tension.

The spring’s design prioritizes FPS consistency and long-term durability, so you can count on reliable performance shot after shot. It’s the perfect upgrade for snipers who want consistent trajectories and stable chrono results in competitive environments.

Easy Installation and Upgrade Path

This spring installs easily in compatible pull-bolt sniper platforms, especially the Silverback SRS-A1. It’s an excellent upgrade for players looking to increase muzzle velocity, improve range, and take full advantage of the modular SRS system. Use a small amount of airsoft-safe silicone grease during installation for optimal results and reduced wear.
