Re: AAC 7.62SD (PING!!!!!!!)
In the 60s Colt/Armalite came forward with the duckbill flash supressor. Look familiar?
It became clear in about 10 minutes that it grabbed everything it passed through and quickly was set aside as a great flash hider, but a poor way to go in other respects. Forty years ago, the solution was, at first to mill a ring around the front prongs and press fit on a steel ring. That sealed off the prongs and ended the complaint. The birdcage flash hider quickly followed when it became clear that flash suppression was acceptable without open prongs. There is no compensation with duckbills at all.
Then in the 2000s we find three prongs again. Without a suppressor they still grab whatever your passs through, though less so in a desert. They still provide excellent flash suppression. With the suppressor on they do what any fork will do...they ring.
Bridge the ends and the ringing is over, provide an internal ring within the can's ID to compress the prongs and the ring is over as well.....or get the other style and be done.
Need the best flash suppression? Use a suppressor. One can only imagine what would be needed to fill up the space between the prongs and the tube to the point were the ring would reliably stop.
I thought I had a transition duckbill around here (pressed ring) if I find it, I'll post it. It would be a simple fix if the dimensions worked within the suppressor.
