M4E1 Builder Set w/ 9.3" ATLAS R-ONE M-LOK Handguard - Cavern Flecktarn Camo

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.

This builder set includes the finished pieces you need to assemble your own Cavern Flecktarn Camo M4E1 Rifle. The set includes an M4E1 Threaded Upper Receiver, M4E1 Lower Receiver and our ATLAS R-ONE Handguard all with this exclusive finish. This finish is available one time only and in limited quantities, so get it while you can!
