Looks like it should work - Presma AR Delta Ring Lever Drop-in Handguard Removal/Install Suppressor Tool

I haven’t actually used this, I bought it along with the new hand guards I ordered just in case I needed it, but I was able to do it by hand. This looks like it would work good, and I like the looks of the coating on it for not scratching your rifle. I bought the version 2 because of the way it goes in the mag well looks like it would work better than the version 1 model.
