the length is 350mm
I don't know what kind of receiver you are building, or how complicated it is, but what kind of machining capabilities do you have? If you have access to a full machine shop and can use carbide tools then you can get a piece of pre-hardened 4140. If you are doing it without a milling machine and good tooling than you best get an annealed piece of 4140 that may or may not need to be heat treated when you are done. I say 4140 because it is an all around good quality steel that is readily available and can be heat treated if necessary.
I have BF20 class hobby mill that i'm planning on using.

It's pretty friggin hard to find anything that's not mild steel. I called many companies around Boston, many don't even stock steel they sell. I was looking for non-mild-steel sheet metal and it's an impossible find.
You may be better making contact and ordering from China. I kid not. US does not produce steel anymore.

It's more expensive, though. Saying that a firearm receiver needs 4340 over 4140 would be a stretch... unless you're shooting space aliens on Mars in sub zero temperatures all day long while holding stresses associated with a .308 locking bolt.

I can get just about anything,but I have the ability to have it delivered,I had a customer that wanted 8 inches of Brass 2" roundstock to turn on a lathe...I had to buy 12 inches from the supplier and now have a 3" paperweight as I didn't want to charge the guy for it and he wanted it exactly 8 inches.
