depends on if you are going to use the junk mags that came with your notos , i knew immediately that i was going to replace mine with Carm , but it has been over a year since i got my notos, & i can not remember for sure , but i think i went with high rings , someone else with a better memory, will come along & help you, good luck & have fun, when i received mine, all of my other A/G were not getting used anymore..
