The December Builder Sets are here to finish off the year strong. This double feature brings two different colorways to the classic flecktarn camouflage pattern that is the basis for many disruptive camouflage patterns across the world.

A Cavern Flektarn finish by Nevada Cerakote brings a darker colorway to Flecktarn giving it a much more subdued look. The Arctic Flecktarn finish by Weichel Performance Coatings takes this same pattern and gives it a winter camouflage colorway. Whether you are building a rifle for your next sub-zero hunt, or just want something that stands out from the rest-this month's release has something for you.

NOTE: The Arctic Flecktarn sets have a minor cosmetic imperfection that is not visible when the Builder Set is assembled. This cosmetic imperfection is on the inside surface of the handguard that contacts the barrel nut. This blemish has no effect on performance or aesthetics when the Builder Set is assembled into a complete firearm. Due to the nature of this imperfection, we will not be selling these at a blemished rate.
