Steel or Aluminum rings (?) / NF or Mark 4(?)

[ap3572001]

Looking to mount a suggestion on rings . Heavy 300 win mag rifle and a NF 5.5-22x50 scope. Thinking about getting either NF or Mark 4 rings, Would go with aluminum or steel?

I like the NF ultralite rings on my 300 Win Mag hunting rifle.

I have no experience with the Mark 4's but I use the NF Ultralites and have zero complaints.
