Looking for recommendations on better 16 inch barrels that meet the following:
- .223 Wylde or 5.56 NATO chamber
- Midweight profile
- Midlength gas system
- Barrel material is chrome-moly or stainless; no chrome lining
- Extension is hardened or nitrided; no nickel-teflon or similar coatings
- Budget is $200-$300


Below are some of the barrels that I found, in no particular order:
