M110 spring - GD

The GUARDER Progressive Spring – SP-110 is a highly reliable component for upgrading AEG replicas. It is made of tempered Si-Cr alloy (oil-hardened) and, thanks to its progressive (irregular) winding, compresses more smoothly, which not only increases its service life but also reduces wear on the mechanics. This design contributes to long-term performance consistency — the spring offers an output velocity of approximately 104–110 m/s (SP-110). Thanks to strict performance ratings, you can expect reliable results that match the specifications, unlike lower-quality springs. Features Progressive winding — smooth compression start, optimized performance Material: tempered Si-Cr steel (oil hardened) — excellent resistance and durability Performance: 104–110 m/s (SP-110) Consistency: consistent performance even after thousands of shots Compatibility: standard AEG gearboxes, less suitable for PSG-1, SR-25 models
