I have a lower I have built with a CMT tactical billet lower, SSA-E trigger and an a2 stock

I have a mur upper with a bcm BCG that I have been trying to decide what to do with.

Decided to build a Grendel. I have lots of heavy barrel precision ar's but I want this one to be relatively lightweight for nighttime hog hunting. I have been studying the available barrels and I think I have made a decision. The satern cut rifling barrel. They have an 18" medium contour, it still has a .875 diameter at the gas block, but nowhere can I find what it weighs. Don't want another hbar barrel. Don't want a noodle barrel.

open to advice
