The Browning BT-99 is ideal for American singles, handicap trap, beginner and veteran shooters alike. Three key features set the BT-99 apart from all the rest. The Invector-Plus interchangeable choke tube system provides consistent, dense shot patterns in the constriction needed for your shooting situation. Its Vector Pro Lengthened Forcing Cone 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 chrome-plated chamber is to resist the toll thousands of shells and corrosion resistance is also greatly improved. The BT-99 also utilizes a bold beavertail forearm, extractor, and high-post, 11/32" rib. The Micro is designed to comfortably accommodate smaller shooters. It features a Graco adjustable comb and butt pad plate, steel receiver, vent rib barrel with ivory front and mid-bead sights, gold-plated trigger, and includes one M Invector-Plus flush fit choke tube. This 12 gauge model has a 32" barrel.
