FPS Softair AEG Spring M105 Compact and reliable, the FPS Softair AEG Spring M105 is a high-performance upgrade spring designed for dedicated airsoft enthusiasts. Calibrated for precision in Italian craftsmanship, it’s ideal for players who run mid-length barrels and D-type cylinders. Calibrated FPS: 105 m/s (about 345 ft/s) when used with a 363 mm inner barrel and Type D cylinder. Barrel & Cylinder Compatibility: Optimized for barrels from 301 to 400 mm and Type D cylinders; calibrated for a typical setup around 363 mm. Barrel Length Impact: Shorter barrels will reduce FPS, while longer barrels can increase FPS within the supported range; calibration assumes standard conditions. Bearing Influence: Calibration does not account for bearing thickness. Expect roughly +2.5 m/s FPS variation per bearing (spring guide and piston head) in real installations. Made in Italy: 100% Italian-made, developed in collaboration with leading companies in the sector for quality and traceability. Durability & Reliability: Designed for repeated cycling with attention to consistency, helping maintain stable performance over time. With the M105 spring, you gain a predictable power profile that supports consistent shot groupings when paired with the intended barrel and cylinder. It simplifies tuning for field play, reducing the need for frequent adjustments when barrel length or bearings vary. The Italian-made quality and collaboration with industry leaders translate to durable materials and careful workmanship, making it a solid choice for upgrading standard AEG setups and building reliable mid-range performance.
