I rest my case. You are clueless. You also missed the part where filing down the disconnecter, or not replacing it if it gets warn out, will allow it to go into uncontrolled fire emptying the whole mag in one shot regardless of what you do with the trigger.
You could do the same thing to a Browning A-5 shogun if you were dumb enough.
But don't let that slow you down Ace. You are batting 0-10 so far.
You never had a case.
