looking at maybe upgraded my suppressor. There seems to be alot of different thread sizes ? I think my current thread might be 9/16x18 (older gunworks).
It will be on a 7mmo8 and will be getting a new thread put on.
So my question is what is the most common thread size that is suitable for a 7mm08??
Hi,
Muzzle diameter is more critical than calibre itself, ie. the muzzle has to be thick enough to leave a proper shoulder behind the thread.
If the shoulder is not enough, mounting and removing the suppressor over time may damage/shape the shoulder and your accuracy/zero will suffer.
Here is our simple guide to recommended threads:
| Ase Utra
Basically most bolt action rifles could be covered with the three metric thread examples, thinner than 15.5 mm then with for example 1/2x20 or 1/2"x28 UNEF.
The PDF file in the link then shows our tolerances for the two main metric thread types on suppressors, Sako or no spigot type and the spigot type thread.
Why we call the no spigot thread the Sako thread is that we worked together with Sako on introducing their factory threads, as other manufacturers use them also we may switch the designation to just no spigot.
As mentioned, several European rifle manufacturers use one or several of the mentioned threads, U.S. manufacturers usually then of course relying on imperial ( 5/8"x24 UNEF for example is very common )
Best Regards!

5/8x24 is a very common size for factory rifles, but will typically only be for slightly thicker barrels.
1/2x20 is also common if factory rifles, but of you are getting a thread cut go for something bigger.
You generally need 1-1.5mm of barrel thickness left for the suppressor to locate against.
Most sporter rifles will allow a M14x1 or M15x1 thread, the biggest thread I could get on my Tikka was M14x1 and I have seen a lot of rifles/suppressors for sale with this thread.
As mentioned above there are different factors that can affect thread choice. It needs to have enough depth to have a register when it hits the end. It also needs to leave enough barrel atthe bottom of the thread to maintain a structural integrity. A 1/2unf on a 375 will end in tears....literally at the bottom of the thread as it will make it a spiral cut and not a thread.....
The rifle is a good quality tikka;)
9/16x24 (14.3)is the most common we do on standard tikka , if you get your barrel trimmed under 18" then you can jump up to 5/8-24.
14x1,15x1 are all good as well.
Gunsmith today recommended 14x1
just got my 243 done in 14x1
all threads on my rifles are 14x1Quote:

I'll join in, mine are 14/1 as well. Seems popular.
Comes in handy having the same thread on different rifles, just don't go the wrong way and put a big pill through a small hole.
I have a Forbes 20B ultra light 308 haven,t suppressed it as the barrel is a 21"Forbes custom number 1 contour barrel so pretty light gauge the rifle is light and well balanced as it is nice to carry and shoot and am worried that i could wreck this rifle if i suppressed it ,how much do you cut the barrel down and what is the the best light weight suppressor to buy to try and balance the rifle up again or am i barking up the wrong tree?
i just turned 60 and have been told that the hearing in my right ear is now on the way out if i don,t start looking after it!
i have made the first move to try and help my right ear by changing the furniture in the house so i can sit on the right side of the misses so she can only yell in my left ear
the other option i suppose is go to the ear doc and see what sort of hearing devise i can get that will enhance my hearing when hunting and cancel out hi volume noise
the other advantage is i could wear them at home as well so that,s a plus plus when you think about it
the down side is the hearing devise will be bloody expensive to buy, so will have to sell the new furniture for deposit on it and that has consequences in its self because i will only be able to earn 80% of the wage i get now on ACC after the misses rips my nuts out himmmmmmm there could be silver lining to this senario do ACC still pay out lump sums for missing body parts
i,ll have to look into this a bit further and talk to my mate google about this i think
but in the mean time your wisdom and knowledge on this subject would be much appreciated on what i should or you would do?
!/ do nothing and go deaf
2/ fit a suppressor and possibly wreck my nice rifle and go slowly deaf
3/ buy a very expensive set of noise cancelling ear whodakys
4/do both options 2 and 3 and get my nuts ripped out
Option 5.
Sell the Forbes, buy a Finn Light, fit a DPT or A-Tec then keep calm and carry on.
Go deaf then it won’t matter. If you use a light dpt it won’t change the balance too much. You can get a titanium one for $1000 and it only weighs 150 grams
Both my 243's are 14x1 and my rimfires are 1/2 unf.
Think 14mm is good for up to 30cal none magnums then go bigger.
Have seen some suggestions that bigger is better when possible due to heat retention and metal expansion issues.
The threaded muzzle tip holds a lot of heat due to the silencer preventing cooling.
Same, picked up a DPT over the barrel for my 243 in 14x1Quote:
