With the Nucleus integrated rail platform, the Umarex Surgemax Air Rifle is engineered to reduce scope movement and vibration, which can hinder the accuracy. The included 4x32 airgun scope will be gripped steadfastly, preventing it from slipping and preserving its zero, shot after shot. The tactical all-weather synthetic stock has a rubber recoil pad and a sculpted ambidextrous check piece. The 18 9/10” blued finish break barrel has a TNT gas piston and a single-shot cocking mechanism with a two-stage adjustable trigger and an automatic safety. The air rifle is 48 8/10” in overall length.
