GTTom Posted September 27, 2020 Posted September 27, 2020 I'm thinking of getting the Briley One shot extension. Since I have the Carlson Breaching choke I think there will be enough length on the barrel but Briley's web site doesn't give any specs on how long the One shot extension is. Anyone have one that they can measure for me? Thanks ! Quote
Vertigofirearms Posted September 27, 2020 Posted September 27, 2020 Won't work. You need the factory or nordic components. Quote
aznwhip Posted September 27, 2020 Posted September 27, 2020 It's too beefy. I tried it with my OEM brake and wouldn't clear. Anything short of same diameter as the barrel will result it clearance issue. Quote
GTTom Posted September 27, 2020 Author Posted September 27, 2020 Great, thank you guys. Good thing I checked? Quote
Sigma05 Posted September 29, 2020 Posted September 29, 2020 I run the Nordic +1 in conjunction to the factory choke/brake. With that combo there’s plenty of room to spare. 2 Quote
GTTom Posted October 2, 2020 Author Posted October 2, 2020 (edited) I already have the choke so not inclined to change it out. I'm still curious so I sent an email to Briley to see if they would provide the dimensions on their One Shot extension. Edited October 2, 2020 by GTTom Quote
GTTom Posted October 17, 2020 Author Posted October 17, 2020 (edited) Follow up on this thread: I contacted Briley tech service and they sent me a CAD drawing of the One Shot with measurements. It was a 1:1 sketch so I printed it, cut it out and using it as a template it looked like it would fit. Ordered the One Shot extension and it came in last week. it FITS! For clearance I have to install the One Shot extension first then screw in the Carlson choke. Just enough clearance doing it this way. Now that it it fits I had to address the issue of not getting the last round in the magazine. Thanks to the info from @Birdog19 post in this thread I was able to shorten the magazine spring without a lot of trial and error. Shortened the spring to 16" sticking out of the magazine and it fit 8 rounds but it felt like the last round was binding the spring just a bit. Cut the spring back to 15" and it leaves some clearance after the last round. Good to Go! I'll hit the range tomorrow and runs dome rounds through it. Pretty happy with the outcome though.

GTTom Posted October 20, 2020 Author Posted October 20, 2020 (edited) Went to the range yesterday. Everything worked great. No problem loading 8 rounds. Not FTF. Ghost loaded 10 rounds. Boy was that fun? Action shot of my buddy who emigrated from Scotland. He sent the photo to his friends in Europe titled" Sunday morning Merica!". You can see the flash pattern from the breacher choke. Edited October 20, 2020 by GTTom 2 1 Quote

As gm2376 mentioned , there is no C clip used with extension. Since the spring isn't captured by a clip it can take a little practice to remove the extension without the spring flying out. There is a small hole in the end of the extension. I stick a small screwdriver in the hole which helps to capture the spring in the extension while you screw it off. 1 Quote

Dkay67 Posted December 21, 2021 Posted December 21, 2021 Looks horrible with that Carlson breaching choke, imo. Too cramped, aesthetically. The textures are all over the place too. The Nordic is the way to go 2 Quote
Lakotah Posted March 21, 2023 Posted March 21, 2023 I know it’s been awhile on this post but does anybody know the overall length of the extension? Quote
