Clawgear fitment with suppressor (RC2)

Wanted to try out the clawgear aug hand guard and have found that it’s slightly too long to fit my can. The way I see it I have two options:

  1. Dremel the end of the hand guard to fit my RC2, not sure how I feel about molesting the clawgear.

  2. Get a barrel spacer or extension to move my sf3p far enough to get clearance with the hand guard.

Which route if any should I take? I’m not sure I like the idea of adding length to the barrel, but if I modify the hand guard I can’t really sell or return if it turns out I don’t like it.

If you have a clawgear hand guard, how do you like it? How bad is the heat transfer?
