This is a factory Ruger magazine for the Pre-Mark I or Standard Mark .22 lr, 9 round capacity.
Please be advised that this is an original Ruger Mark magazine, this will only fit your firearm if your original magazine has the same solid chrome bottom as the one pictured. These firearms were not stamped "Mark" anywhere on the firearm because they were the predecessor to the entire Mark Series.
There are multiple styles of the Mark I magazine, please double check the picture to make sure this magazine matches what you are looking for.
Shall we say it again? DOUBLE CHECK your firearm and magazine, pull it out of the safe and BE SURE this is the magazine you need!
