I just ordered a Thunderbeast 30P-1 for my 6.5X47. The can will have the standard 5/8-24 threading. I also have a couple of .223's that I would like to use it on as well. Would I be correct in thinking I could get the same thread pattern since they have heavy bull barrels?
 
Re: Threading For Suppressor

There is nothing magic about the thunderbeast 5/8-24 threads, so yes, you can cut threads on your other barrels.

I think thunderbeast dislikes anybody but thunderbeast threading a barrel for one of their cans.
 
Re: Threading For Suppressor

Just had my TRG-22 cut and threaded for a new TBAC 30P-1. Mark Gordon from Short Action Customs did the work and it was done to perfection. Short Action Customs is a TBAC dealer and that is where I purchased the can as well.

I believe TBAC simply wants any barrel threading done to class 3 thread specs and gauges used to determine thread fit - not the suppressor. You can probably get the specs from TBAC. Just make sure you have a very capable/reputable smith do the work. Not something you want to have doubts about.

They want to make sure the threads are cut to their specs to ensure proper line up of your bore to baffles. You have slop in your thread job and it shoulders poorly the suppressor could come loose. Any competent smith with the right tooling can do a good job. GAP and SAC have always threaded my barrels for me and done an excellent job.
 
Re: Threading For Suppressor

As previously stated, they want them cut to Class 3 specs. I had my gunsmith personally talk to them over the phone before cutting my threads, and thankfully all turned out well. I will say that I was a little concerned beforehand, but after thoroughly checking before the first shot I didn't have any problems. They (Thunderbeast) were more than helpful during the process and imagine they would be the same for you. They're big thing was to not cut the threads according to the suppressor, but to cut them to class 3 specs instead. Good luck.

Not using a certified 3A ring gauge when threading muzzles is asking for problems later in life, like a stuck suppressor for starters

Gemtech is the same....if they didnt cut your barrel...dont ask for a refund if you get a baffel strike.

The first staement is True. There is nothing magic about cutting 5/8-24 threads to mount a can. Any competent gunsmith should be able to do it. A ring gage is nice but not nescesary, a thread mic will work, PD wires also, and just using the can as a gage has been done by many gunsmiths and will work. The problem with not using some way of measuring the thread is that it may be slightly oversized and a different can may not fit and get stuck on the thread. Gaging is prefered as several have stated. The main thing with fitting a can is that it needs to be a true 60 degree thread form, done true to the bore, and that you have a good square shoulder to butt up aginst, somthing any good gusmith should be able to do.

The second statement is False. I know for a fact they are plenty busy making cans and don't need the extra work of fitting them all. They would just like to see them fit correctly so they are not having to do alot of repair because of a stuck or crooked can. They are happy to have the help of all the competent gunsmiths fitting their cans.
 
Re: Threading For Suppressor

I have all the gauges one could have for measuring threads. However, I always feel more confident on a job when I measure with wires. They give me a number to write down for the record. Final check test is a ring gauge.

If the threads on the suppressor are Titanium, especially grade 9, have the smith add a thou of tolerance in the clearance. A close fit and a warm barrel when taking it off and you run a higher risk of suppressor stuck to barrel.

This is a shame too. You can have the best smith in the biz thread a barrel perfectly and when you try and thread the TI Suppressor on, the heat from a rapid twisting motion locks it up.

Seen this happen on the range many times. Grade 5 Ti is less likely to do this.
 
Re: Threading For Suppressor

The length of the thread is important also. Too much and you will have carbon building up on the threads that extends inside the can. Too little and you have carbon building up inside the threads in the can. All the barrels the can is to be used on should be the same. Working to the manufacturers specs will help prevent a supressor from becomimg siezed onto a barrel. This is where using a gunsmith that has done a few and knows the little tricks of the trade is good.
