Hey Mike. Welcome to the forum and thanks for you interest in the wrench. PM inbound.

Hey man, thanks for sharing. That is an interesting option. Is the barrel you put back on a finned barrel or un-finned? Only curious because I imagine a smooth Thompson barrel would have less friction with the wire leash than a finned barrel would. Im glad it worked for you but I too would have my doubts that it would always work. Not hating on the idea, it’s a cheaper option that might be worth trying. I will say it is nice having a dedicated tool that you know works every time.

I just posted a quick tutorial video on YouTube on using this wrench. I know I am a visual person and it makes way more sense watching the video than it does following the instructions that I send with each wrench. I know there are other wrenches out there, such as the Doug Richardson wrenches, which I believe have more pieces and they are machined out of a block of tool steel. No doubt those wrenches are more solid. I developed these new wrenches to be a cost effective alternative to Doug’s awesome and proven design. Some pertinent info: - This wrench will work with - finned or non finned barrels. - barrel diameters from .970-1.005. -1927, 1928, M1A1 receivers Reach out with questions or comments.

As far as I know there is no torque spec for Thompsons. There might have been from the factory… Found this quote from reconbob in another barrel install /removal thread here on the forum - “ The square thread of the Thompson can't be torqued very far once the shoulder of the barrel hits the receiver. Once the shoulder hits, maybe you can turn the barrel 1/8" and then it just won't go much farther. Unlike a V thread where once the shoulder hits you can torque the barrel maybe 1/4" or more. So when you barrel a Thompson you can turn it on as tight as you can before your barrel wrench starts to slip. Bob”

Right on. I’ll shoot you a DM. personally, I didn’t use anything to protect the barrel on my project. The I.D of this wrench is .995. You could use some painters tape which is about 5 mils if you have a barrel that is closer to .985. My barrel ended up being .995 on the money so I didn’t use tape and I didn’t end up with any concerning witness marks.

Thanks for your interest as well. Just sent you a DM -Connor

Thank you. I’m glad you like it. You could always scale it down to a 2x3 and keep it in your wallet lol.

Found this image of an old 1928 Thompson add. I decided to blow it up onto a poster to see how it would turn out. Overall I’m pretty happy! The 20x30 posters at Walgreens were the same scale as the original image. I was also happy to find it didn’t get too blurry after scaling. It be cool to print this on some old tarnished parchment paper if that is possible. Now I have a cool new garage poster and conversation starter. After all, the cost of the Thompson set the stage for the GCA tax stamp cost. If I frame it, my wife said I could even hang it in the house some where too which isn’t a bad deal. Just wanted to share this idea. The original image is attached if anyone else is interested in making their own. The poster cost was $26 from Walgreens.

I am very happy to be shipping these barrel wrenches out this week. Thanks for the support thus far! Let me know if you are interested in a barrel wrench! One of these was an extra and is for sale.

Hey @Steve45just sent you a DM regarding the wrenches. I’ll have a few available for purchase by the end of next week. That is interesting about Apex’s response. I know for a fact that I have a smooth bodied M1A1 barrel in my 1927 A-1 receiver. I haven’t tried a 1928 square finned barrel in the 1927 A-1 receiver though. Edit, I just found this on the royal tiger imports website regarding their 1928 finned barrels: “These will also thread into M1A1 Thompsons and function, however an M1A1 front sight does not thread on to this barrel (M1A1 sight pressed & pinned instead). “ so it seems all Thompson barrels thread into the 1927, 1928 or M1A1 receivers and the differences arise in the muzzle (threaded vs unthreaded). 1927 and M1A1 are pressed and pinned muzzles whereas the 1928 barrels have a threaded muzzle. I had a pressed and pinned cutts comp on my 1927A-1 barrel though so Kahr must make cutts comps that are threaded and some that are pressed and pinned. Regarding your 14” permanently attached cutts comp. I took my cutts comp off the barrel prior to sliding the wrench on. There might be a chance that I could get the wrench over the cutts comp without removing though. I’ll try that in the morning. Connor

Also to your previous question. here are some links for the shorter barrels. apex has non finned https://www.apexgunparts.com/thompson-m1-m1a1-barrel-10inch-new.html royal tiger imports has finned and non finned https://royaltigerimports.com/shop/1928a1-thompson-45-acp-10-5-finned-smg-barrel-parkerized/ I also make barrel wrenches for removing and installing new barrels if you are interested in one. I’m currently making one for @Jimbola23as he stated above. I have a link to that here if interested.

Correction. You only need to send the atf 2 copy’s of FP cards. Not two sets. My bad.

Hope your finger prints went alright. It’s usually pretty easy here in Reno. If you E-filed you only need to send in 2 sets of fingerprint cards + your atf cover letter. The cover letter is one of the attachments in the email from the atf after you complete your transaction on the eforms site. Back when paper forms were common, two copies of your submitted form-1 were sent to the atf with 2 sets of FP cards and the cover letter, and one copy of your submitted form-1 was sent to your law enforcement agency you choose. So there were always 3 forms but only two sets of FP cards needed. Maybe that’s were the 3 came from you are thinking about. it’s important to note that you only need to send your law enforcement agency the law enforcement copy of your submitted form-1. To my knowledge this does not have to be the approved form-1. The law enforcement copy does not require your photo or fingerprints. Hope this helps.
