There have been several different models of Sears 12 guage pumps- most common were the model 20's and 30's. The model 21 did have a vent rib and an adjustable choke- was made by Flight King for Sears. In guns, condition drives a MAJOR part of the value. The 27th edition of Gun Traders Guide indicates a selling price of ABOUT $125 for good condition, up to about $225 for new in box. The Sears firearms tended to be for shooting, not collecting, and as a result, their prices are not screamingly high. I DO have a couple that I still shoot, and they do that very well.AnswerA bit heavy, but very stoutly built, the Higgins model 20 with the removable power PAC choke tubes was made by High Standard from the late 40s through the mid-late 50s & can be found at most gun shows for $125-$150.
A barrel with a full choke.
A shotgun barrel with a cylinder bore choke.
Yes- that is what the poly-choke is for.
You don't give us the model, so it is hard to answer the question. Assuming the gun does not have an obvious adjustable choke, the choke is probably not easily adjustable. A gunsmith can open the choke (from Full to Modified for example) or can install internal interchangeable choke tubes (costs around $125).

If you mean a choke bored barrel, it designates the amount of constriction a shotgun barrel has.
Yes. Slugs are not a good idea, due to potential damage to the adjustable choke. Buckshot should be fine.
They came in various barrel lengths and choke combinations. If it is not marked on the side of the barrel, you will have to pattern the shotgun to determine the choke
In most cases, the makers do not recommend it. With some adjustable chokes, the "fingers" that make up the choke can be damaged by a slug.
The Choke of a shotgun is the amount of barrel restriction at the muzzle end which affects the shot pattern. A full choke will keep the spray pattern of the pellets closer together farther out than if the barrel was not restricted at the muzzle. If there is no restriction at the muzzle, the choke is said to be cylinder choke or cylinder bore.

They probably denote what choke the barrel has.
It is possible to fire a shotgun without a choke, but it is highly not reccomended, and they don't cost that much If you select a barrel with no choke (cylinder) it will cause the pattern to be looser than for a barrel of a shotgun that has a tighter choke. The extreme is "full choke" which keeps a tight pattern out to the effective range. Full choke is typically used for waterfowl. A shotgun that is pressed into double duty (shot for small game and slugs for big game) would work well to have modified choke. Slugs have to be designed to fire through a full choke without blowing the barrel but you will certainly shorten the life of the barrel by firing slugs through a choked barrel. If you can afford an extra barrel, then use a cylinder (no choke) for slugs. Remington and other shotgun manufacturers have interchangeable choke tubes (see link) that allow you to screw in the appropriate choke for your quarry.
choke of sears model 20 12 gage plain barrel shotgun has 3 stars on barrel
No. A choke tube slips into and screws to the muzzle end of the barrel. It can only decrease the inside diameter.
Either a full choke,or extra full choke shotgun barrel.
A choke is a device placed on the end of a shotgun barrel that changes the pattern of the shot as it leaves the rifle.
the barrel is constricted at the end to make the pattern of shot flow density wider or tighter. Usually from cylinder up to full choke
Tubes that constrict the column of shotgun pellets as they exit the barrel
It is called "choke". lcj
Approximate value on this shotgun is $130 - $200 depending on condition.
