Ruger began adding the "warning" stamp on the left side of the barrel after some safety and liability questions occurred in previous years. The time in which the stamping began was in late 1977 to early 1978.
It is the serial number. Ruger's web site has sn data on it.
USA if you mean Ruger.
There is no such model number assocaited with the Ruger Bearcat. Do you mean the serial number is 918?
It's the rising Phoenix.
If you mean a Sturm Ruger, about 300 USD
If you mean a Ruger Model 96, $300-$400, depending on condition, box, papers, etc.
If you mean a ruger, 100-600 depending on specifics
The numbers 10-21133 are the serial number that was assigned to your Ruger Standard Mark I pistol,which was made in the year 1969.
If you mean the Mini-14, it will get the job done within its limitations.
The "77" in Ruger 77/22 refers to the model designation of the rifle, indicating it is part of Ruger's 77 series, which includes various firearm models. The "22" signifies that the rifle is chambered for .22 caliber ammunition, which is commonly used for small game hunting and target shooting. This model combines Ruger's traditional design elements with a focus on versatility and accuracy in a .22 caliber firearm.
Depends. If you mean the Ruger Mini-14 or Ranch Rifle, yes, you can. It is chambered for .223 and 5.56x45 ammo. If you read the owner's manual (available on the Ruger website) it will tell you that on page 13. The Target Model is ONLY for .223. Of course, the 6.8mm and the Mini-30 use different ammo entirely.
I think you mean RUGER, NOT luger red lable..........?
