Caesar Guerini Says:   Should you adjust to your gun …or should it adjust to you? The new Summit Impact allows the shooter to adjust all critical specifications making it easy to fine tune the gun to their shooting style. Point-of-impact, overall weight, stock fit, trigger system, recoil characteristics, and balance are all customizable. The geometry of the Impact allows for an upright shooting stance, making your gun mount more comfortable while reducing felt recoil. The result is less strain on your neck and shoulders allowing you to concentrate on only the target. The 17mm tall tapered rib dramatically increases target visibility.  The Impact is the world’s most versatile clay target gun carefully designed for the worlds best competitors.

Advanced features of the Summit Impact:

•D.T.S. Rib adjusts from 5% low to 90% high by simply turning one screw. •17mm tall D.T.S. rib allows for a more up­right and comfortable shooting position while improving visibility. The Impact rib is 40% lower than our trap rib but, offers many of the same advantages. •The Impact comes standard with the D.T.S. adjustable comb™ with patented 7 way adjustability and index screws for fine calibration. •New D.T.S. trigger system with two trigger pull weight options, take up, over travel, and length of pull adjustments. •Optional D.T.S. Barrel Balancers allow weight to be added anywhere along the barrel in seconds.
•Satin blued finish with Invisalloy™ clear protection. •Satin blued barrels and rib to reduce glare. •100 % of our barrels are tested and certified for correct point-of-impact regulation. •All stocks are pre-fit for the optional D.T.S. Kinetic Balancer system with mul­tiple weights and micro adjustment. The system also includes kinetic recoil reduction and does not need to be removed to access the stock bolt when removing your stock.

Hero's Arms Says:  This is a beautiful and very functional 20 Gauge competition gun.  I sold it new in 2014 to a friend who is a Vermont Gunsmith.  Over three years he fired it fewer than 500 shots, when asked "Why?" he said, "I have lots of guns".  He added a Kinetic Balancer in the stock ($175), Barrel Balancer Weights ($175), and two Extended Competition Selecta Choke tubes $122) for a total of $472 additional investment. He also sent it to Caesar Guerini for a Pit Stop and had the trigger pull reduced to 3 pounds 5 ounces, and the over travel reduced, giving it one of the crispest triggers I have felt.  I list it as As-New-In-Case but it should more properly be, Better-Than-New-In-Case. At eight pounds 9 ounces it is heavy enough to make 20 gauge recoil very modest.  This gun can fit almost anyone, for almost any kind of clay target shooting.  It now comes with eight chokes in Improved Modified, Light Modified, two Improved Cylinder, two Skeet and two Cylinder constrictions.  It has a 14 7/8" Length of Pull, adjustable by moving the trigger, and a slight right hand palm swell, to complement the cast off (for right handers) stock.
