Detailed Features
The back-bored vent-rib barrel reduces felt recoil and smooths shot patterns compared to standard bore dimensions. The Invector Plus choke system ships with Full, Modified, and Improved Cylinder chokes, which covers most hunting and range situations without additional purchases.
TruGlo Long Bead fiber optic sights aid target acquisition in dim early-morning light. The chrome-plated chamber and bore resist corrosion and simplify cleaning after wet outings. Textured grip panels on the synthetic stock maintain hold in adverse weather conditions.
