I never use recoil systems on my guns. I simply take off the butt pad and replace it with a 1" thick kick-eez pad and I'm good to go. My KX-5 shoots real nice with good patterns produced from the steel chokes, but I purchased a titanium choke for it and upped my scores by 2 to 3 birds.
Got mine in May and love it. Raised the comb 1/4" and am good to go. Shot my best score ever in the caps(98) and my singles average with it is up 3 birds. I might just try the K80 Combo now. Factory chokes are fine for me now, I use a #3 for singles and caps(24yds) and won't change until my cap scores fall off. Good luck, Al Baker
I love mine it has a Jones adjuster and no other mods. I use the factory steel choke tubes #2.5 from 16 yards and #3 for caps(25yards). The factory steel chokes although short produce great patterns and just destroy targets so I feel no need to upgrade them. I shoot mostly 3 dram loads and don't feel the gun needs a recoil reducer even after shooting 300 targets in a day. I feel the KX-5 is one of the best single barrel target guns available and I would reccomend it with confidence.
Have been shooting and enjoying mine for 3 summers now.
My changes from stock were a Gracoil and a new pad.
I use the number 2 choke at 16 and the number 3 at 23.
Old Browning Broadway for doubles choked 16 and 25.
I've had mine for three years now. Only dislike was the factory recoil pad. Replaced it with a Kick-eez modified trap pad. I use a few aftermarket extended choke tubes. Did I need them? I thought I did, however others are happy with the factory tubes. I shot my best scores with the KX-5. Bill
