Our new enhanced lower parts kits have set the standard when it comes to out-of-the-box mil-spec performance. All black parts in the kit are phosphate coated. We do not use coatings that will rust over time like black oxide. If you're using a drop in trigger, this kit contains everything else needed to complete the lower excluding the stock components.
