The complete Nickel Boron BCG also goes well with our ST Battle Trigger as it's also coated in Nickel Boron. The Trigger group isn't needed but it's a nice added touch and a huge improvment over a stock/standard Mil-Spec trigger group. It makes the action super smooth when the hammer and carrier are both coated in Nickel Boron.
