People love shiny things and will pay more the reflection.
As a target shooter I see extremes. Some rifles are beat to hell, spray painted barrel to save money by not paying for bluing, dented stocks, or covered all over with glue. Such as this M1a.:
Other target shooters, their rifles are perfect, not a dent or scratch on anything.
While appearance matters to many, to all, group size is the most important and no one shoots a pretty rifle that goes not group them in the middle.
So what is important to you, are you willing to pay more for the shine, assuming it shoots as well as a non reflective rifle?
