Sorry guys, complete newbie!
"Regulated", as in, fitted with a regulator. A device that regulates the pressure of the air upstream of the inlet valve, and is supposed to make the shot-to-shot consistency a lot better. The idea is that it takes out the variation caused by the inlet valve having to work against a higher pressure at the start of the charge and then opens for longer toward the end of the charge.

Also, the most problematic and cussed piece of kit fitted to a pcp.

Modern UNregulated rifles like the AA S400 don't really need them. As long as you are prepared to learn where the most consistent section of the charge is then a regulator not required as you only get 10-15 fps variation within that. An S400 charges to 190bar, but you probably dump the first 10 shots, then get 50-60 "good" shots before the charge start to be exhausted. A regulated rifle would probably give you 80-90 shots across the charge.

My comment on an unregulated carbine is that the cylinder is smaller, so the number of consistent shots come down. Regulated rifles cost more and have more problems.
