They are still being made
Side-by-side shotguns are still manufactured.
who makes the westernfield model m550a 12ga shotgun
Not enough profit.
For a specific answer, please provide the model number. Most guns stopped production in Belgium in the 1970.
The last Marlin made shotgun was the Model 512 slugmaster,which was made from 1999-2001. After that Marlin made no more shotguns.
they stoped making the 4 bolt main 350 in 2002 hope that helps
It is a long action that has limiting spacers included. The magazine has a spacer at the rear and the bolt has a different bolt stop that prevents the bolt from moving to the full long action length. So I have been told.
Unsure of your meaning of "break away shotgun". If you mean breakdown shotguns like double barrels they continue to make several different models.
Sears never made firearms. They "branded" firearms from firearms makers with their name as part of a contract.
Because the bolt stop is broken..they have a plastic bolt stop.
If you mean the bolt release, it's on the bottom left side of the receiver, away from the bolt handle. From the rear, insert a small screw driver, or other suitable device, and press down on the release while extracting the bolt. The bolt just slides in to reinstall (it presses the release for you).
They aren't though. They will keep making more.
