Guarder SP160 Spring

Guarder is a Taiwanese brand that makes strong Gearbox parts with good precision and quality control. Because of this, Guarder has a solid reputation as a parts manufacturer. Brill Armory is proud to add a variety of Guarder products to our inventory. Guarder springs are made of Oil Quenched/Tempered Si-Cr Alloy Steel Wire and are generally considered to be some of the most consistent springs on the market. These springs are rated to their actual power and are not mislabeled like some ACM springs on the market. Please note that the final AEG power output is dependent on a ton of factors, and as such Brill Armory cannot guarantee a certain FPS. Some factors include compression, inner barrel length, cylinder type, inner barrel diameter, BB's used, bucking/hop-up parts used, and tappet timing.
