RRA NM Barrel VS. Standard SS Hbar Barrel ?

[Hylander7]

I just orderd a Standard A4 20" Stainless Steel Upper.
Will that barrel be the same barrel they use in the NM A4 Upper ?
Their desciption for the NM says Air gauged 1:8 Heavy NM barrel.
Description for the one I ordered says Air gauged 1:8 Hbar
When I check for barrels, They only offer one SS 20" Hbar.

Call RRA and ask. I'm pretty sure it's the same but no point guessing, just call them.
