Hi, I know this thread is old but I have a question. I bought an AR10 Aero .308. I went to test it out and got only a click on the trigger. Couple Times I was able to pull the charging handle and eject the round but other times I had to mortar the rifle to get the round out. Using cheap 147 gr .308. Magazine is 7.62x51 pmag. Could magazine be the issue? Never got it to fire. Only other time I had this exact issue was when I tried using subs in my 300 blackout without a suppressor. Makes me think it could be a gas issue but hoping it’s just the ammo I was using but really have no idea. This is my first AR10.
