This is a factory Ruger BX-25 clear magazine for the 10/22 .22 lr, 25 round capacity. This magazine features one side that is completely clear so that you can visually see the remaining amount of ammunition in the magazine.
The BX-25 has a maximum capacity of 25 rounds and features an angled feeding mechnism to ensure that you get the same feeding reliability as you did with the origianl 10 round rotary mag.
You can also disassemble the magazine in order to clean it, which is a major improvement on its predecessors.
