The Stoeger ATAC Suppressor .177 Cal. Air Rifle with 4x32 Illuminated Red/Green Scope features up to 1200 Fps with alloy pellets. This high-tech performance air rifle with AFC (airflow control) and dual-stage noise reduction system makes for one quiet air gun. This system combines an internal air-regulator ring and baffles that work together for the ultimate noise reduction air rifle. The air-regulator ring has four decompression holes that bleed off most of the compressed air before the pellet enters the baffles. The remaining compressed air dissipates throughout the baffles further reducing noise. The Monte Carlo-style black synthetic stock features checkering and dual raised cheek pieces. This beginner friendly air rifle features an automatic safety, textured pistol grip, and forearm. This high-quality Stoeger air rifle was designed for short-range target practice and small game hunting.
