I had the Dissipator at the range last week when I decided it was time to have a little fun. I fired about twenty rounds through it, "bump fire" style. I found it easier to do than I'd expected, but there was no way I was hitting the target.
Anyway, I laid the rifle down to cool off and moved over to my 10/22. A couple minutes later a fellow drives up to the firing line from the clubhouse and walks over. "Is that a Class III?" he asks.
"Nope," says I.
"So you just fired it that fast?" he asked.
"Yep, bump fired it," I replied, thinking I am about to catch some flak over it.
"You don't have one of them trigger things or nothing?"
"No, just fired it from the hip." I break it open to show the stock DPMS post-ban parts.
"Oh... I really hoped it was a Class III. I don't get to see them very often and somebody said they heard somebody shooting one down here." He gets back in his car and drives back to the clubhouse.
I guess it takes some practice to learn to hit anything with this "technique." I suppose a laser would come in handy here.
