I have a GunThings, and the handguards did'nt go on any harder (Or EASIER, for that matter!) than they ordinarily do.
Well in my case, the handguard cap was not installed properly. Evidently, the person who installed the front sight base wasn't aware that a gas tube would have to be able to go through that hole in the cap and into the hole in the front sight base, else he would have aligned the holes before calling it good.
The handguards not fitting is a different issue, and is a problem with the NOS handguards themselves (some plastic will need to be filed), because the well-used handguards that came with the parts set
do fit, though they are cockeyed (but that is because the handguard cap is cockeyed).

yeah, cap is probably stuck to the backside of the fsb from being parked while assembled...douse it in oil (PB Blaster would be best) and let it sit for a day or two then just grasp the fsb in one hand and the cap in the other and give it a hard twist..I wouldn't use a hammer to try and move it as it's only tin, and you'll probably bend it if you hit it.
It is steel actually, but rather thin. I tapped on it with a rubber mallet. It didn't bend, but it didn't budge either.
Mark's idea of using something to pry it might work ...try carefully using as large a drill bit/nail as will fit into what's showing of the gas tube hole as a lever to move it in the right direction
That's one of the first things I tried, even before posting about it; but it quickly became apparent that it wouldn't work; and additional force would only deform the hole.
