msr15 barrel exchange

[MaddHatter]

how hard would it be to screw on a new 7mm barrel chambered in 7x33 sako for the msr15? everything else looks like its plug and play the case i am useing to make all of my 7x33
cases out of are 350 legend cases that use .223 rim size dimension and the COAL will be a little shorter than 5.56 nato round.

It can't be any harder than changing a barrel on any other ar-15.
