The Northtech Defense Titanium Forward Assist is a precision CNC machined part to fit all Mil-spec upper receivers, both forged and billet. Manufactured from high strength grade titanium that reduces the weight by 40% over standard steel Mil-spec forward assists. The forward assist button, rod and shell are titanium while the bolt pusher is heat treated chromoly alloy (to a Rockwell hardness of 45HRC) it’s then black oxided for added wear and corrosion resistance. This is a must have piece that not only makes the Northtech Defense billet upper standout but other uppers as well. A serious upgrade for the AR10/AR15 platform due to it’s construction, materials and stylized design throughout.
