Seeking Clarity on Thread Pitch for HK Mark 23

Hey everyone,

I’m currently looking into getting a suppressor for my HK Mark 23, and one of the crucial factors I need to confirm is the thread pitch. I’ve done a bit of research, but there seems to be some conflicting info floating around. I’m reaching out to see if anyone in the community can shed some light on this issue.

Key Points I’m Considering:

  • Thread Pitch: What is the exact thread pitch for the HK Mark 23? I’ve seen mentions of both 16x1 and 1/2x28, but I’m not sure which one is correct for this specific pistol.
  • Suppressor Compatibility: If I know the thread pitch, how can I ensure the suppressor I’m considering is compatible?
  • Aftermarket Barrels: Are there preferred aftermarket barrels that offer a reliable thread pitch for attaching suppressors?

Why This Matters:

Understanding the thread pitch is critical for anyone looking to modify their firearm with accessories like suppressors. With the right information, we can make well-informed choices about our gear. Plus, having the correct pitch can save us from potential headaches down the road when we’re trying to attach components.

I’ve been researching the HK Mark 23 thread pitch, and it’s critical to get the right specs. The metric thread pitch is 1.0mm, and diameter is usually around 16mm. Always double-check these with calipers!

When measuring pitch, you can use a thread gauge. Just align it with the thread and it will show the pitch directly. Hope this helps, @dustinbailey!

For the HK Mark 23, remember to measure at several points to account for any wear on the threads over time. Consistency is key!

Yes, @fergusonpamela! I’ve noticed that too. It’s best to check the manufacturing dates and specs if you can.

You can usually find detailed specs in the manual or on HK’s official site. But if you lose it, welcome to the club! :joy:

Ha, @edward40, that’s so true! Manuals have a way of disappearing when you need them most. Anyone have a digital copy to share?

I think the thread pitch and dimensions are quite standardized. Mine has stayed consistent over years of use. What about yours, @lisa94?

11

It’s definitely tricky sometimes. I’ve had issues where it seemed off, so I recommend always verifying with a metric conversion chart if unsure.

12

My Mark 23 was built in 2020, and I’ve measured it three times now; still coming out at 1.0mm! Curious about others’ experiences with different years.

13

Glad to hear yours is consistent! Mine has varied though. Maybe I’m just bad at measuring? :sweat_smile:

14

Make sure to clean the threads well before measuring. Any debris can throw off your results!

15

Great point, @adamramirez! I once measured with a bit of debris in there, and boy was I confused by the inconsistent results! Let’s all take a moment to appreciate thread maintenance. :joy:

Just remember that when in doubt, contacting HK directly is a solid option for official specs, especially if you’re looking to upgrade parts.

I’m glad to see this topic! The HK Mark 23 has a 16mm x 1.0 thread pitch, which is crucial to know when selecting muzzle devices. Many suppressors will fit, but it’s best to confirm compatibility directly with the manufacturer.

18

Thanks for that info! I recently got the AAC Ti-RANT 9 suppressor, and it works great with my Mark 23. Highly recommend it!

I have heard that some people prefer using compensators instead of suppressors, mainly for shooting stability. Have you guys tried that?

I like compensators too! I use a G42 Comp by Taran Tactical, and I’ve noticed much less muzzle rise when shooting. Definitely worth trying if you want better control.
