Product Description
This upper offers a 1/7 RH military twist rate. It is also made of 4150 chrome-moly steel with chrome lining and HP tested. The upper is Mil-spec and at a length of 16" it's pretty darn short. We recommend a 55gr or 62gr bullet for best accuracy. The front sight is a A2 with bayonet lug. If you would like a complete upper please select your Bolt Carrier Group and Charging handle in the options above.
