Lol, i dremel'd the front sight gas block on my mid length upper down to make a low pro cause the flash hider is pinned and I wanted to install a ff tube myself. I was pretty nervous about it, never having done it before, but damn if it didn't turn out fine!
Did exactly the same thing. Worked fine.
HA! I used the dremel, hacksaw, file, beer, alumablack etc.... technique too. I cut a notch in my Troy Alpha rail so the Noveske Switch Block would clear. Mine is a 20" SPRish setup. It turned out "OK". Will try to post some pic's over the weekend. Not recommending that OP do this. Usually not doing as I do is good practice.
OP, will the FF tube slide over the Switchblock now (i.e. without the slot)? If not, you're going to have a heck of time putting it together even with the slot.
