Thanks.

I have a fixed A2 front sight on my M&P 15 Sport ii,

like this:

Just a moment...



but I upgraded to a MagPul M-Lok freefloating hand guard.

On 4/21/22 at 12:34 PM LRB1200 implied that a scope wouldn't work. I'd rather not buy a new upper, instead mounting the optic on the Sport ii.

And thanks for pointing out that the scope is only for rimfire; I'm going to adjust the question above to reflect this scope:

VX-Freedom 2-7x33 Hunt-Plex | Leupold

What do you think about that scope for my M&P 15 Sport ii in 5.56 NATO?
