I'm getting all the parts for a 18" rifle gas system build and messed up by buying an M4 stock and buffer. Would I be correct in tha I need a rifle buffer and spring?

Naw, in fact I used that very setup for about 5 years. Just remember, if it's a carbine stock, you need a carbine buffer and spring, it it's a rifle stock, you need a rifle buffer and spring. Putting a rifle spring in a carbine stock makes it act pretty funny!

You should be good to go with what you have.

Thanks for the quick replies. This will be my first complete build looking forward for my barrel to arrive and to get started.

I had a 16" middy that I had a carbine buffer system, ran fine. Swapped for a rifle buffer system, still ran fine.
Lots of people get confused in thinking the buffer system has to match the gas system.
They are seperate and can "mixed" so to speak.
You can have:
Rifle Gas with a rifle or carbine buffer system.
Mid Gas with a rifle or carbine buffer system.
Carbine gas with a rifle or carbine buffer system.
You just can't mix parts within the system (like Spiff said), no rifle spring in a carbine buffer tube.....etc.

As a side note, some rifles will work with a rifle spring in a carbine tube with a carbine buffer, but it will be very difficult to pull the charging handle and will leave oneself scratching one's head about why the rifle is suddenly short stroking about 1 of every 100 rounds. This typically arises when one THINKS one ordered a carbine spring from Brownells. This may result in one blaming one's magazines until one SuperUncleKurt arrives clad in cape to properly diagnose the situation. If this is to happen, hopefully one SuperTonyWall is on hand to lend/give/sell one the correct spring.
Of course this is a hypothetical situation.
This hypothetical situation also only happens in the early to middle portion of a 1000+ rnd class.
