Thread: Gunwork incl. Barrel threading in Auckland

Hi all, thought it would be worth sharing as most of what I was initially told about barrel threading was, “take it/send in to DPT” which would be a bit of a mission for me who lives in the Northern Auckland region.

I can confirm AB Reid Tool and Diemaking Engineering based at Unit 8C/89 Ellice Road, Wairau Valley, Auckland 0629 do threads on firearm barrels.

I dropped a rifle off in the morning and picked it up about 6 hours later. Alan (sorry not sure of spelling) seems to be a good man and keen to help. He is a firearms enthusiast and the price of the job was reasonable too.

Depending on what rifle you have and whether the shop needs to assemble and/or reassemble the rifle the price should be around the $100 to $150 mark.

Know the thread you want or need. Otherwise Alan can look at it and tell you what thread will work and you can shop afterward.

Hope this helps someone out.

Cheers

Not saying this is true of your guys but I had a rifle cut and threaded by a Auckland GS, then some mths later got around to buying a can and took it to DPT. Immediately told me they would have to recut the thread, loosing another inch of barrel, because the shoulder was not suitable for their suppressors, and by implication, any decent suppressor. Thereafter when I got rifles threaded locally, I took one in done by DPT as a template. No issues thereafter and DPT themselves praised the job " done right". fwiw.

About to get a Kimber cut to a more ‘normal’ thread - do you mind posting a picture of how the shoulder should look in DPT’s view please?

I’d be keen to see as well. I was wondering myself how much shoulder there should be.

I didn't undercut the threads on my rifles like this (Personal preference) so it's likely that is what @Jhon encountered. Any suppressors I've made have the internal thread recessed so it's not an issue but maybe DPT don't make theirs like that. In that case a DPT wouldn't fit my rifle as it'll foul on the thread before it hit the shoulder.

All of our suppressors feature an internal thread relief of approximately 2.5mm in length. Occasionally, we encounter issues when muzzle threads lack a relief cut. These problems often arise due to the non-threaded section being excessively long or having a diameter larger than the threaded portion.

reloaders also has a good smith

Just out of curious, is that kimber brand new?
