Thompson barrels aren't the easiest to remove/replace due to their thread pattern, and the design of the grip mount bar .....to do it right requires specialized tools.
Once the new bbl is installed, you'll need a very good drill press, or mill to drill your front sight, or compensator/sight, for the cross pin. My advice is once your F1 comes back, send it to Bob Bowers at Philadelphia Ordnance, or Dan Block to swap it out ...... |

What's the deal with the Thompson pistols? Maybe I was reading it wrong but it seemed that you couldn't get the form 1 and just slap on the stock. It wouldn't accept it. Is that wrong?

Is that wrong? Its actually easier to adapt an M1 or 1928 Grip frame to a '27 than it is to modify the original semi "lower" |

I have an Auto Ordinance M1 Thompson which I bought because that's what my father carried in the pacific.
I keep thinking getting a short barrel and SBR it just to get it closer to that configuration. I'm definitely tagging this thread, doing it myself is beyond my skill level. |

Quote HistoryQuoted: Wasn't Auto Ordnance selling SBR's at some point? I swear I saw them I am almost positive it was at least "offered" by them... whether they made any and/or sold them I don't know. Seems Thompson FA prices were stalled, at least last time I looked 18 months ago. I'd say swing for the fences instead. If you think its something you will keep forever and have an heir who will want it, go for an SBR if you really want... Otherwise, I say just buy a pistol version and just pull the trigger real fast from the hip. |

In my experience the AO version isn’t worth buying a stamp for. Spend your money on a real gun of some other kind.

I have 2 Thompson sbr’s at my house. The first began life as a 16” M1 model. I registered it then installed a GI spec short barrel. I did that about 10 years ago and still regularly shoot it. A few years ago I decided to try another route. I bought one of the pistol versions of the gun. I liked the idea because it already had the short barrel and the receiver was made out of aluminum. The grip frame required a good bit of material to be machined off the rear tang to be able to mount a buttstock. I had to drill and tap holes for the screws. I’ll send detailed pics of what I did if anyone is interested. Send me a message. I don’t know how to post pics on here.

I got the factory sbr in 2008, Taiwanese drums work perfect in it, wasn't a cheap date even back then

Buying one of the rifles and having the barrel swapped is cheaper than buying the factory SBR. Add in the time of a form 1 vs. form 4 and it's a no brainer. I had mine done by Dan Block in Iowa and had him do the quick change barrel mod. With the mod the barrel is snugged, instead of the original full retard tight, and a set screw is added to the underside of the receiver to lock the barrel in place. I did this to have the option of going from a traditional look to a threaded barrel for use with a can or to return it to 16" if I ever wanted to sell it.
