Have you ever said to yourself, “You know, I love my Ruger 10/22, but how can I take it to the next level of fun?”

I think we’ve all asked ourselves that question.

When it’s time for the answer, ring up the wild and crazy guys at, who know that “Fun” means a trip back to the laugh-a-minute days of the bloody St. Valentine’s Day Massacre, the party atmosphere of Okinawa and the swingin’ times of Anzio.

That’s right, is where you can guy a conversion kit to give your Halloween costume the ultimate air of authenticity: a Ruger 10/22 that looks just like a Thompson submachinegun but fires inexpensive .22 LR ammo, eliminating the annoying skyward barrel creep the Thompson is known for and making it much cheaper to shoot just for laughs. Can you imagine the green Al Capone would have saved on that day in 1929 if his men had pumped out 70 rounds of .22 LR (about 5 cents a round in today’s market) instead of .45 ACP (closer to $1 a round).

More importantly, can you imagine the looks on the faces of your friends down on Castro and Market when a pigeon crosses the street and you haul this mother out from under your trench?

Made of aluminum, steel, and American walnut, the Fun Gun Kit requires no machining and no trip to the gunsmith. Plus, since some Thompsons originally came with 50-round drums in the heady days of blowing away cattle rustlers with this puppy, if you order the Fun Gun Kit with the 50-round drum magazine, the late Senator Edward Kennedy will personally rise from the grave and deliver it to your front door with a signed statement that he’s really sorry he helped ban high-capacity magazines in 1994,  and he understands now that freedom comes from the barrel of a Thompson replica, especially for zombies.

Actually, I made that last part up; not just the magazine ban apology and the zombies — the whole thing. Ted Kennedy won’t rise from the grave, and the federal assault weapons ban expired in 2004. However, the 50-round drum that comes with the “Chicago” rendition of the Fun Gun kit is a dummy, as is the 20-round magazine that comes with the (far more common in its day in the actual Thompson) “Squad Leader” configuration. Needless to say, the weapon continues to shoot like a regular 10/22, with a patented, detachable 10-shot rotary magazine.

Here are the two other configurations of the converted Ruger 10/22:
