No It is not a repeater , you must re cock and and hand load a pellet after each shot!
Check YouTube for Marksman Repeater, I have found several that show you how to take it apart and put it back together
To obtain an owner's manual for a Marksman 1790, you can start by visiting the manufacturer's official website, where they may offer downloadable versions of their manuals. Alternatively, you can contact their customer service directly for assistance. Online forums and dedicated airgun communities may also have user-uploaded resources or tips on where to find the manual. Lastly, searching for the manual on websites that specialize in vintage or discontinued products might yield results.
I would start with Beeman air gun co. They own the Marksman line of air guns (See the link below) or go online and look up "air gun repair" and locate someone near you to repair the rifle. Or see the link #2 below.
To load a Marksman 1790 series pellet rifle, first ensure the rifle is pointed in a safe direction and the safety is engaged. Open the breech by breaking the barrel down, then insert a .177 caliber pellet into the breech with the pellet’s skirt facing the barrel. Close the barrel securely until it locks in place, and then disengage the safety before taking your shot. Always follow safety precautions and manufacturer's instructions when handling the rifle.
The duration of The Marksman is 1.58 hours.
Zero. Crosman doesn't make Marksman, Marksman does. The Marksman holds around 18 BB's or 1 pellet or dart.
I would search the web for "Air gun Repair" and locate a shop near you that can repair it or see the link below for shops that repair air guns.
The first national census of the United States of America was in the year 1790. It has since been completed every ten years; but not until the 1850 census did the census-takers ask the names of every member of the household. Up until then, they only asked the name of the head of household and the number of inhabitants.
