What are the specs on the barrel (metal spec, twist, etc.). Micro Lite gas block? Is this package from Sig, or aftermarket??

We package the Romeo5 with the upper. The upper comes from Sig. The barrel is nitride coated. This has a carbine length gas system. The upper weighs 3lb 5oz and has a 1 in 7" twist. The gas block is Sig's and we believe it is the M400 low profile gas block.
