Unlike other airgun manufacturers that utilize only sound dampening baffles, Stoeger's X20 Suppressor utilizes the Dual-Stage Noise Reduction System™. By combining the functions of an internal air-regulator ring and baffles that work in tandem, noise is reduced better than any other airgun on the market. The air-regulator ring has four decompression holes that bleed off most of the compressed air before the pellet even enters the baffles. The remaining compressed air dissipates throughout the baffles further reducing noise.
When tested in a certified anechoic chamber by F-Squared Laboratories, an independent testing facility, Stoeger's X20 Suppressor proved to be as much as 7.05 decibels quieter than the competition's "quiet" airguns.
In velocity comparison tests the X20 Suppressor not only achieved the highest average velocity among the tested airguns, but also, produced the most consistent velocities, important for attaining optimum accuracy.
The X20 Suppressor comes with a quality Stoeger 4x32 compact airgun scope with an illuminated reticle. The scope is factory mounted with rings that attach directly to an integral dove-tail located on the top of the receiver.
