Threading tikka fluted barrel?

[thinhorn_AK]

do you recall the weight loss before the can at the end?

No, I don’t really pay much attention to the weight of my guns.

I sent mine to kampfeld, he did great work and I got it back in about ~ 3 weeks.

Beautiful. I'm looking to do something similar and will check him out. What bottom metal is that?

I had my T3X superlite threaded a few years back. 1/2x28 is doable but gunsmith recommended 9/16x24. A little less conventional but left more meat on the barrel. I don’t think 5/8 was an option for mine, plus I think 9/16 is on the smaller side for a shoulder to seat your muzzle device on.

Good luck! You adding a brake or can?

Someone like kampfeld can install a shoulder into the barrel to make it 5/8x24.

Looks great! I hope to find somebody in Michigan that can do this cheaper than just buying a new prefit.

I have been told these guys do it in Lansing when I chatted up the owner at an archery event.

Is there any reason to worry about 9/16 threads? Thunderbeast has my 243 super light right now and I want it cut like the one above and the guy at the counter says it’s only thick enough there for 9/16 because they don’t like to go 1/2-28 on anything over 22 cal. My plan was to just pick up a forest thread 9/16 hub for my harvester evo’s rather than try to run an adapter then the can.

I can’t see a benefit of going 9/16 other than making your life more difficult. It’s kind of a bastard thread pattern for finding anything for.

I did 1/2-28 on my 243. I’d love to know their explanation for not running 1/2 on anything bigger than a 22 other than it just being some unwritten industry standard.

That’s the Main reason I believe then there’s the fact it’s a super light with a small diameter barrel.
Here’s what I got in an email from them but I don’t really understand the systems they are telling me they can do. All want is threads I can direct thread onto even if that means I need to pick up a new direct thread cap for my harvester evo from silencerco.

It’s at their place now and has a note for when it’s my turn in line for the machinist to call me so we can discuss my options once they get the information they need from actually measuring it themselves

“We do not recommend 1/2" threads for any rifle with a bore larger than .224". It does not leave enough barrel wall material to safely support a suppressor. We do have a couple of solutions to use your Harvester Evo with that rifle. With a barrel OD of .636" we can thread it in 9/16x24 and install one of our Face Mount CB Brakes, and with the addition of our CB2HUB Adapter, you could have a brake mount suppressor. Alternatively, we have a Face Mount direct thread adapter that we can install that will allow you to direct thread your suppressor on 5/8x24 threads while providing an adequate shoulder. We are currently out of stock on the Face Mount direct thread adapter but will have more in about six weeks. We could perform the Face Mount CB Brake right away”

And this is why I don’t like TB.

Here is how I read what was written to you.

“We recommend against something that literally every gun maker has done because we want to sell you some unnecessary crap that will make your suppressor system weigh more. Our premise for this goes against years of people using suppressors on 30 cal barrels with 1/2-28 threads without an issue, but trust us bro. Don’t worry about the extra money or the fact that if you want to use that suppressor on any of your other rifles you will have to change back to the original HUB or buy more of our unnecessary junk. Oh and our lower price option is out of stock, so you should go with the option that requires you to buy all of our accessories, or wait longer. Your choice”

What you need to do is politely ask for your gun back and then send your barreled action to Kampfeld to be threaded 5/8-24 with a collar. It will save you a good bit of money and headache.

Yeah, i've got a couple tikka lite profile barrels finished at 18" with 9/16 threads because that gives you adequate shoulder and is larger than 1/2". Hub and other adapters are definitely a little more of a PITA vs 1/2 or 5/8. If doing over id have had shoulders added and gone 5/8".

Yeah sounds like blowing smoke up your rear…. Those threads can’t support 10.8 oz of weight? I’m not an engineer but I’d love to see the data behind this…

From past discussions I think they are more worried about you dropping it and bending the end of the barrel with the added leverage of a suppressor hanging off the end. That in theory would be bad. Has it or does it happen? Don’t know.

 

[HighUintas]

Bbobs statement above is why I had my barrels threaded to 5/8 and a shoulder installed (except for the 223). I just want extra strength.

But in a 243, I absolutely wouldn't hesitate to get 1/2 threads and use a 5/8 adapter

 

[Tjdeerslayer37]

I am also interested in this, I just ordered a Roughtech Ember superlite 6.5 PRC and a Mcmillan "Mountain Tracker LR" would love to cut it down to 20 inches or so to help balance my can. I am located in Michigan.

magnaport threaded mine in michigan, but i didnt have them go down to the flutes

No reason as far as safety and function. I was just tired of dealing with adapters so I had them shouldered. The first 2 I did were done by shaen custom rifles but he stopped taking work so when I sent my tikka superlite in, I went with kampfeld.

They look like this:

Thanks for that and all the other responses once the machinist calls I’ll ask him some more questions and see if something like above could be done
