I have 3 of the A1 Carry Handles and really like them.
The plastic nuts included with the handle from CNC Guns are garbage, so you need to replace them with real steel carry handle nuts.
I used A2 apertures with the A1 components.
The one I have on my 9mm has the XS same plane aperture since I don't need the range changing aperture..
+1 - Except for the nuts, the CNC Guns carry handle is good kit. I put same plane apertures on mine because I rarely get an opportunity to shoot past 200.

What I'd LOVE is an A1 with quick release leavers instead of the protruding screws.
Yea, a Larue made A1 carry handle would be the heat.
I am a big fan of the DD A1.5 fixed rear BUIS. It is on the gun for which I bought the CNC Guns unit. It's tough enough and super light.
