I mean no offense by any of the following, but I find it very odd that someone thinks a 10/22 is more work to clean than an AR.
Regarding the barrel, clean it with a flexible cleaning rod (Otis) to prevent crown damage, pulling it from the chamber to the muzzle. Also, be very sparing with the cleaning of the barrel, since cleaning a .22LR barrel tends to be much more abusive than shooting it.
Regarding the necessity of removing the stock to remove the bolt, this is true of every semi automatic and automatic long gun I am aware of. There is no getting around it, except with an AR platform where removing the stock (lower reciever) does not affect the barrel. This is one of the reasons the M21 (accurized M14) was doomed as a sniper system, they are entirely too hard to keep match grade accurate.
On a standard 10/22, the reciever pins are like 1/8th inch in diameter and 1.5 inches long. I can't speak for the Volquartsen, but this is much larger than, say, the extractor pin on an AR.
Regarding the spring assembly and bolt, put the spring assembly in, compress it with a screwdriver next to the spring/op rod, and hold it compressed by putting your thumb on the actual charging handle portion. Drop the bolt in and wiggle a bit, and it goes right in.
As for taking longer to clean, my "not going to be shooting this in the forseeable future" cleaning of the 10/22 takes about an hour. The same cleaning on an AR takes about 6-7 hours split over several days, involves, at a minimum, a trip to Wally World for the 500 pack of Q tips, a can of brake cleaner, a pair of forceps, a set of dental tools, a knife to scrape carbon off of the bolt, and, occasionally, several pots of boiling water.
Both will be clean enough to perform surgery off of by the time they actually see the safe.
I have to ask, if you find the 10/22 to be a 9 and the AR a 3, I'm curious what you're not cleaning on the AR. Either that or the Volquartsen has absolutly no internal similarities with the standard 10/22.
