I had a 16 inch upper of there’s. It would barley do 2 moa. So I decided to replace the barrel with a 18 inch core rifle systems. When I went to take off the barrel nut from the BCA (I purchased a complete upper) I noticed that it took very little torque to remove, maybe 15 psi (I’m a mechanic) food for thought. I’m shooting the rebuild this Saturday
