The BT-99 Plus is the embodiment of the regal trap gun. Not overstated, but simply elegant, the BT-99 Plus has a polished blued finish and high relief engraving on the receiver. The stock is made from grade III/IV walnut with a gloss oil finish. This gun is also a performer, with a ported barrel, Midas Grade Invector Plus choke tubes, an adjustable comb, and a high-post rib for maximum target visibility. Like all BT-99s, the Plus has a chrome-plated chamber to resist the toll thousands of shells can take on lesser quality guns. Corrosion resistance is also greatly improved. Longer, tapered Vector Pro dimensions minimize shot deformation and maximize pattern uniformity, consistency and density. Back-boring increases bore diameter specifications and decreases friction between the shot cup and the bore to maximize shot pellet velocity and reduce felt recoil. The Invector-Plus interchangeable choke tube system provides consistent, dense shot patterns in the constriction needed for your shooting situation.
