I have not seen any pictures, and I do not have any Keymod or Mlok gear - so its hard for me to answer this question from just looking at some pictures. I would like to add rails to the top, and adjacent to the front rail section built into the handguards.
How close can the m-lok or keymod accessory rail get to the built in front rail section? I am hoping it will be continuous. It appears it will be.
The attached rails are then same height as the front rails I assume? (the pictures I see are just at weird angles, and I have not seen any pictures of a rail accessory on the top yet).
The reason I ask is because I want a light on 12:00 O'clock position, a space for a thumb a c-grip, and then a back-up folding sight. I don't know what light I want up front yet, either the Inforce regular or the XL. But in general, I'd like them to be continuous rail sections. I am going from a a carbine setup to a rifle upper build and I really don't know how that might change my support arm position, so if it is continuous I can easily make changes (other handguard makers want to get fancy and have made it so that there can not be a continuous rail setup on their lightweight versions)
