The Winchester Model 101 Ultimate Field Over/Under Shotguns are fast-handling, smooth-swinging designs, made in Belgium to traditional Model 101 dimensions. At the heart is a low-profile steel receiver that enhances quick and instinctive shooting. With the low-profile receiver, recoil occurs in-line, directly back, reducing muzzle jump for faster follow-up shots. A Pachmayr® Decelerator® recoil pad absorbs recoil also aiding in getting off rapid second shots, while reducing shooter fatigue in the field or on the range. Invector-Plus™ interchangeable choke tube system works hand-in-hand with .742 back-bored barrels to reduce shot deformation and promote uniform shot patterns. Hard, chrome-plated chambers and bores provide surfaces that are highly resistant to wear and corrosion, and clean easily. The Winchester Model 101 Ultimate Field Over/Under Shotgun comes with a finely finished walnut stock and forend with 20-lines-per-inch checkering that provides both elegance and a nonslip grip. All metal components are machined to exact tolerances, and the wood-to-metal fits are extremely tight. Field shotgun comes with three Invector-Plus choke tubes (Full, Modified and Improved Cylider). Sporting shotgun comes with five extended Signature tubes (Full, Improved Modified, Modified, Improved Cylinder and Skeet).
