View Full Version : M261 .22lr Magazine Question

07-21-2008, 1:21 PM
I recently acquired an M261 .22lr conversion with a 10rd magazine that inserts into a .223 mag. I don't have any .223 mags yet as I am in the process of my first AR build, but I am worried that the .22lr mag will be too long to fit into a 10rd .223 mag (I have only heard of people using them in 20 and 30 rounders). Is there a way to modify a hi-cap mag body so that it won't accept .223 and then use it for the .22lr insert? Has anyone else had this issue?

you can use just the spring without the follower if you want I have a 20 and 30 round magazine with m261 inserts in them but you don't have to.
