I'll give you a bit of contrary advice, compared to previous posters.
1. Buy a video or paper manual that is good enough to allow you to field strip or disassemble your firearm a bit to get at the moving parts.
Especially before firing it for the first time, get to know your rifle and
make sure all the parts are there! Clean off all the parts (incl bore) with the solvent of your choice, lube with the lube of your choice, then head to the range.
My wife just bought a Rossi 92 in .44mag (yeah, my 5', < 100lb wife owns a .44mag) & it was missing the firing pin collar. I have one on order. Especially WRT used guns, make sure it is safe before firing to the best of your ability.
2. WD40 is not of the Devil.
It is not the best cleaner, lube, protectant, but it'll do unless your weapon is capable of fully automatic fire, where it gives up WRT lube faster than other possible choices.
I baby my arms with products generally superior to WD40, but my dad & grandpa used it exclusively on their arms, none of which was a rusty mess or had a malfunction due to build up of any sort of sticky stuff (and all of which I now posess).
FWIW:
1. Carb cleaner or brake cleaner are cheap gun scrubber replacements at 1/4 the price (keep it off the wood & plastic, though)
2. Synthetic motor oil will lube & protect very well for real cheap...some use it to clean, too
3. Ed's Red is a fine solvent, unless you need to remove jacket material or heavy lead fouling.
4. CLP/Breakfree is a good all-around product.
IMO, stop worrying about the "Ultimate" cleaner, lube or protectant. So very few people live in climates or put their weapon to such heavy use as to NEED the "Ultimate" product...or anything better than a mediocre product used regularly.
