We begin by gun-drilling the most accurate hole, when keeping next to zero tolerance (TIR), that allows every other process to follow suit. Moving on forward to our proprietary precision base bore reaming, precision 6 groove rifling, final bore remaining, and on through the manufacturing process. Northtech Barrels are (high speed machine fluted), this allows for almost no metal removal per machined depth pass, (therefore keeping the integrity in the rifling). Our barrels are CNC-chambered in .223 Wylde, Heat-treated and Cryogenically treated for cold/hot barrel performance. Each Barrel has the highest quality barrel extension, including M-4 feedramps, and of course feedramp hand polished. The chamber is also polished and actually chamber honed. Each Barrel comes with a sub-moa capable guarantee on a 12 inch length, or longer barrel. We have actually achieved accuracy of 1/2 moa on our 10.5" barrel length, however that requires all aspects to work correctly and the operator and everything else must be must be capable. With every Northtech product, we push to the next level.
