Are handguards over top of suppressors really usable?

How big is the ID of that rail?

The TP is pretty large.

I have the extended suppressor rail for my Sig MCX, and was really hoping to use using it over my Trash panda (Whenever I get approved) but I have always been concerned with heat and so on.

Hell, even after a little bit of my BCM 11.5 with a 556 can that gas block gets super hot and makes it uncomfortable to have my hand near.

I will measure it when I get home. Might not even be possible it sounds like. I have not physically put my hands on my TP yet, so my estimations might have been bad going into my idea

The Trash Panda suppressor is larger than most at 1.75" OD, which makes it perform great, but won't fit under most hand guards.

I have a 6” 300blk with a screw on can under a handguard. I’ve done a couple of mag dumps using subsonic ammo and it’s not too bad. Don’t think I would do it with 5.56.

Also, as someone stated, can’t really shoot the gun without the can.
