This air gun also features a multi-grip system allowing the operator to personalize the style of their grips, ProAdaptive checkering that allows the air gun to feel like a natural extension of their bodies, and an S3 Suppressor to significantly reduce noise.
Stoeger introduces the next generation of airgun technology in its fast shooting, hard-hitting, yet quiet S4000-E. It comes with multiple features to customize the fit and feel, including MGS and ProAdaptive Checkering technologies. The integrated S3 suppressor dramatically reduces shot noise. A recoil-absorbing buttpad makes shooting a joy. Other features include an ambidextrous safety, adjustable two-stage trigger, and interchangeable fiber-optic bars for the front sight.
