Sabre Defense barrels any good?

[Creeky73]

I am looking for a good quality 20" barrel with the rifle length gas system, with the 1:7 twist rate and M4 feed ramps. I am not seeing too many of these online, that are from manufacturers I care to buy from anyway. I would rather not use the Noveske or Rainer barrels as none of these are black phosphate coated that I can see, and they cost a bit more than I wanted to spend. Sabre Defence has one at Rainier, and the price ok for me, but I don't know if their barrels are appropriate for a SHTF type firearm. They seem to cater more towards the target/competition market, right? What is their reputation? Any help is appreciated.

and yes, I misspelled their company name in my original post. but to my credit, the spell check shows "defence" as wrong, so.....
