F/S Rhino Stingers small gauge tubes

I bought these to use in one of my k80s and have since acquired individual small gauge barrels for that gun so I won't be using them. Each gauge has 2 -SKT and 2-LM chokes to shoot skeet/sporting clays. Will work in all 12 gauge break open guns via their O-ring system to fit accordingly. Some guns may need tweeking to properly reset for the .410 gauge. Everything pictured is included from carry case to extra O-rings, instructions, tools etc.... Pristine condition. Offered at $775. Thanks for looking and good shooting, Rey
