Can you dehorn a rail?

So I got this Sig MPX and it feels so silky and smooth and I LOVED it, but then I replaced the aluminum hand-guard with one of those super sexy Carbon Fiber rails and DAMN it feels nice.

BUT, when I bought an aluminum rail that was made for it, the rail wants to bite me everytime I grab it. It does NOT match the remaining part left on the rifle, although it matches up next to it nearly perfect.

How do you dehorn these things? Do I take it off and run it up and down on my wire wheel a few times or is there a better way to do it without removing the finish? Maybe the finish being removed is not so bad...

On my rails that have some burrs on the edges, I put rubber rail ladders on them. It's not as nice though compared to sanding and refinishing.

I always thought they ran parts with sharp edges through a tumbler - pretty sure you've got one of those..

I have the same issue with a co-witness pic rail mount on my PC carbine. very slick machine work, but the leading edge all the way around is fairly sharp. I think my bubba fix was going to be hitting the edges with some very fine sandpapper on a block, to slowly bring down the edge. Followed up with a blue finish touch-up pen, or maybe just a sharpie marker (works well on an AR that I needed to touch up after I boogered a part install)

Understand that I don't really care about the value/perfection of these guns, they're working guns.

for my 1942 Victory Smith...I would take a much more careful approach, and might even send to a 'smith to get refinished.
