"The TriStar Sporting Arms TT-15 Trap Combo Shotgun is essentially two separate trap guns that share one action and stock making it perfect for multiple trap disciplines. It comes with a standard 32"" over/under barrel configuration as well as an ""unsingle"" 34"" barrel configuration that can be swapped in and out. The 32"" over/under barrel set is useful for standard doubles; the 34"" unsingle barrel is ideal for singles or handicap trap. Both barrel sets feature fiber-optic sights along with a raised, adjustable rib that works in conjunction with the adjustable comb to let you set the gun's point-of-impact higher than a traditional field shotgun. The walnut stock features a perfectly contoured palm swell, grip checkering, and generous butt pad for long days of busting clays. Includes 5 color-coded, extended Beretta/Benelli Mobil Chokes (SK, IC, M, IM, F). 2-3/4"" chamber.
