axis AR mag modification?

[ohihunter2014]

Anyone recently do this? I found a few videos with model 10 mags and axis 308 mags using a different type of mag for the job. I am interested in doing this for my axis 223rem.

The 223 is more difficult due to the magazine being blocked. At least that is what I assume. Give it a shot using the techniques used on the 308 mags. Take pictures or video. You can do it!
