I was curious why I couldn’t thread a suppressor on in front of the lock nut the same way the brake goes on, assuming it has the correct threads? Anybody have experience with suppressing an old BOSS rifle? I don’t really want to chop and re-thread the barrel if I don’t have to

I believe if the suppressor is not able to seat onto the shoulder of the barrel and is only seated with threads then you will have an alignment issue.
I see, so basically the lock nut just wouldn’t serve as a precise enough shoulder? The brake has a .338 bore, maybe that gives them a little extra wiggle room for alignment. This would be a .30 cal can on a .243 wssm

Also, a 9/16x24 muzzle indexing brake can be installed for silencer mourning when there’s not enough shoulder if the manufacturer makes one. ThunderBeast makes them for theirs. I use one on my 300WM that Thunder Beast threaded and installed the brake on.

Doesn’t the lock nut and ring behind it for all the way off?
It does but there is hardly any shoulder if taken off. Threads are .560 and barrel is .595
The locknut acts as a moveable shoulder for the brake to seat against, wasn’t sure if same could be done for a suppressor

That small amount may not impact a 2 inch long brake with an oversize opening but could cause a strike with a 6-8 inch long suppressor.
It really isnt an issue to have the barrel cut and threaded. I would personally have it cut and threaded 1/2 x28. Some gun guys will even thread to 1/2 and then install a shouldered extension/adaptor to 5/8 threads like a flare on the muzzle.

There can be alignment issues with using a lock nut or jam nut for suppressor indexing. They can move a small amount, that can affect alignment a small amount.And when doing that it creates more stacking tolerances that may or may not cause the firearm to decrease in accuracy. Correct thread pitch options should be determined by the amount of material between the bore and outer diameter of the barrel.

1. Thread your suppressor on and tighten it against the lock nut.
2. Remove the bolt from your rifle and look down the bore, from the rear towards the front. Center your head/eye to look down the center of the bore. (When centered, you probably won't be able to see any of the material of the suppressor. (The inside of your suppressor, when looking through the inside of your barrel))
3. Move your head/eye to look at the extreme diagonal angles down the bore. (up/down/left/right) Depending on caliber of the rifle and suppressor, you may or may not see material of the suppressor internals when you do this. You likely will. You want to make sure you can see an EVEN amount of material when looking at the 4 different angles. This indicates proper alignment. If you see more suppressor material at one angle than another, you don't have perfect alignment, and this COULD cause baffle strike problems.
What caliber is the rifle and what caliber is the suppressor? If they are matched, (556 can on a 556 rifle, or .308 can on a .308 rifle), the tolerance will be tighter and alignment will be more critical. If they are not matched (.308 can on a .243 or 556, etc), you will have more error margin(tolerance for slight misalignment).

Like mentioned above you may be able to make it work as long as it's not way off. It would have to be majorly canted if your putting a .338 can on a .243 barrel I would think. :dunno:

Oops. I missed that where he said calibers. It's a .243 bore and .30 cal suppressor. That should have plenty of clearance unless alignment is WAY off. I run a 30 cal can on a .243 also. My .243 is threaded 1/2x28 and I run a thread adapter to 5/8x24 to the suppressor.

Just confirm alignment like I outlined above and it should be good to go.

Thanks for the input everybody. I haven't actually bought the can yet, and this isn't the main rifle I'd be using it on it'd just be a bonus if I could make it work on this gun as well. I don't shoot it very often (mostly because its too damn loud :chuckle:) maybe 40-50 rounds a year which is why I don't want to go through the trouble of chopping/re-threading if I don't have to. Guess once I actually decide which can I'm going with that could dictate whether it'll have an adapter availableYou should probably hurry up and buy that can last month! Thats the best time to buy one.

What's the barrel length? If it's 24" you'll end up with a pretty unwieldy, front heavy package after you add the suppressor. I cut my bolt guns 16-18" for standard chamberings and 20-21" for magnums. Worth the small drop in velocity.
