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 SaturdayI alway check the torque on the barrel nut w/my torque wrench before I remove it.I buy BCA uppers for the parts,so do my buddies.I have removed over a dozen BCA barrel nuts by now.They were all torqued over the 40lbs I torque them at.Had to take a torch to several.But,I have had many loose BCA hand guards.At the price they sell uppers,I am sure they have a high demand and have to move them out quickly ,so there will be mistakes.
