WHAT IS AN AR-15 BUILD KIT?

The AR-15 rifle build kit includes absolutely everything that you need for completing an AR-15 style rifle. Choose your rifle length, desired caliber (5.56/300BLK), and customize to your heart’s content! This takes all the parts hunting out of building a new rifle from an 80% lower. This way you get an entire AR-15 build shipped to your door, and all that is left for you to do is mill out and assemble the lower receiver. 

Can’t figure out which caliber you want to go with? Check out our blog on 5.56 vs 300 Blackout?
