May I ask what it is you don't like about choke tubes? Just curious......
I have a model 12 field I customised in 1992 with custom wood, simmons rib, forcing cone lengthened and sent it to Briley and had a set of series 2 choke tubes installed. At that time the choke work was $129 installed with choice of 3 chokes, $20 extra if I wanted chokes with steel shot compatability. I went for the lead shot chokes and later ordered steel tubes when non-toxic shot became mandatory for waterfowl. The installation work was excellent and you'd never know they are there unless you look in the muzzle. They are flush mount, thin wall..ie: no barrel swaging on the muzzle end so aesthetically it appears original. They are without doubt the best patterning tubes I have ever fired and they turned my model 12 into a superb multi-use gun for me. I shoot skeet, trap, waterfowl and upland with it.
