The one you posted looks like it will fit fine, however it will partially obstruct the loading assist.
I got the promag one and it works great, you just have to be careful not to over-tighten it or it will warp the plastic of the mag and the follower will get stuck.
e: also I had to dremel off maybe 1/3" of the screw because it was too long for the 15-22 mags.
