What is the thread size for a Winchester Model 90?
In this model of Winchester rifle,there is no difference in value between the round or octagon barrel.
No
model #24
I need to clean the barrel, not like a model 12.
A Winchester model 1200 field grade shotgun will be between 90-150 dollars for a plain barrel model,100-165 for a vent rib barrel model,and between 140-200 dollars for a shotgun with the Win choke present.
No.
The model number should be stamped into the barrel near the Winchester name. It will say "model" or "model of"
No
Best left to a gunsmith.
Probably Winchester.
