Help deciding 18" barrel

[CCFD1414]

I've pretty much narrowed it down a Mega Arms 18" stainless and a Rainier Arms 18" CHF barrel, with Rainier's Black Friday sale the barrels are about $7 difference.
The main use for this build is for hunting coyotes.

Are you asking an opinion on these two options? You need to be more specific in what you want to know. What kind of distances are you shooting at? You will also benefit from utilizing the search feature, and also looking in the precision semi-auto sub-forum. There you would find threads such as this https://www.m4carbine.net/showthread.php?142316-18-quot-Rifle-Length-Gas-Barrel-Options
