I haven't heard anything about Galati's rectangle cases on here. Talk of such cases usually ends up on the Tac-Force cases (
link 1,
link 2) or the i-SHOT (
link). Most people who have the Tac-Force seem to like them for the money. I looked at one at a shop, but didn't buy it. Only because I need more flexibility in the tie-down positions. (And because he wanted $100 for it when they were $50 online.) Everyone who has an i-SHOT likes it, except for the price. I'll probably end up getting an i-SHOT, but haven't been able to pry the $$$ out of my wallet yet.
The Galati page doesn't say theirs is closed-cell foam, but I'm pretty sure their trapezoid-shaped cases are. I believe those have generally had decent reviews over in the Competition forum. I have one by King, which I believe was a mid-priced Galati line (now discontinued) and it's been fine. Rides around in the truck a lot, but otherwise isn't abused. My dad is happy with his Galati trapezoid case, but he just takes it to the range and back.
I looked at the Bagmaster cases at a gun show, but didn't like that it didn't have separate mag pouches. I looked at the Eagle, but didn't like that it only had 4 mag pouches and that they were inside with no padding between them and the rifle. Blackhawk is another option, pretty much the same as the Galati and Tac-Force. i-SHOT used to have a "Civvy Carbine Case" with velcro in the side pouch and only two tie-down rows for less than the TCC case, but I can't find it on their site now.
