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.
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..........?
Ruger is the name of the company that made the pistol. .380 ACP is the cartridge size. ACP stands for Automatic Colt Pistol- part of the cartridge name, as some of the first of the .380 cartridges were made for use in Colt pistols..
