Duct tape/ Swiss Army Knife ??
Add a bayonet, and in the words of Tom Hanks-
"Houston.........we have a problem......"
First problem is the Tupperware stock that will say aloha if you used a blade attached to the barrel
Second is the attachment of barrel to action is more of a suggestion than attachment. It will also say bu-bye.
Sort of a "Farewell to arms"
Perhaps a Spork and hot glue???
Now, my plans to add a machete to my J-22, THAT makes perfect sense......
