I’ve never fired full auto except with an M60, just to qualify that I could use one when in the military. It must be a hoot to shoot one without a bipod or something to stabilize you. I don’t think I would use full auto for home defense, if I had it except maybe for the psychological effect.
A friend once filled down the sear pin on a 222 Bushmaster, but I never got the chance to try it.
Glad you enjoyed it. If I could, I would do the same.
