OK folks. this is a modern technology invention here. it has ATF approval and listed as a primitive ignition system for black powder percussion locks. It replaces the drum in the barrel and allows us to use 22 nailgun blanks. It features a double safety (one on the hammer and one on the adapter itself. The cost on the nailgun blanks (basically a 22 caliber blank) is $5.87 for 100 at lowes ($0.0587 per shot) and comes in several flavors, the differences being higher the number the more powder in the shell, i.e. #1 and #2 to just replace the percussion cap, #5 and #6 to replace the percussion cap *AND* the main powder in the barrel. You can obtain around 800-900 fps with the #5-#6 blanks.
Here the device is all closed up, in 'safe' mode. You can see the screw that goes into the barrel here.
Here is with it 'open', note the ramp at the bottom of the hole, that will fit under the rim of the shell and pull it out when fired. allows easy access.
Here is a shell inserted.
And here is the shell itself in case many are not up with their design.
Oh and the makers home page if anyone is interested in more info about it.
