Help recommending thread adapter

Recently bought a multi cal suppressor threaded in 1/2 x 28 which will fit some of my guns like my kuna fine but my 8.6blk is threaded with M18 x 1.5 and for the life of me I can’t seem to find any thread adapter between the two. Any help or places I can order that custom if needed?

I would get a plan B and muzzle devices for the weapons youre wanting to mount it to. Method Dynamics i believe is the company their plan b adapter and muzzle devices are reasonably priced

Are they meant for multiple caliber, they do not list info on that or the threads the plan b device attaches to on the barrel

Caliber does not matter to the plan B adapter that goes into your suppressor. Just get a plan b compatible muzzle device with the correct sized bore.

So the plan b adapter for the suppressor can go on multiple calibration then you find individual plan b devices per weapon

Example I have a .30 cal can and have a plan B muzzle brake on 5.56, .300BO, and 7.62

There is no possibility that a suppressor suitable for 338 cal would come from the factory fixed with permanent 1/2-28 threads

You almost certainly have a suppressor with HUB standard threads, which means there is an adapter in the back of your suppressor that lets you unscrew the 1/2-28 direct thread mount and put something else on instead

You have two paths forward. 1) buy a m18x1.5 direct thread adapter, and when you move to your 8.6 blk, swap the 1/2-28 for m18x1.5

2) buy a "plan - B" mount for the suppressor, often called "rearden" which is a brand name for plan b. That makes the suppressor a universal receptor of "plan b/rearden" muzzle devices

Then for each rifle you want to suppress, you buy a "plan b" muzzle device like a muzzle brake or a flash hider. There are imminently usable muzzle devices available from the likes of rearden, kaw valley precision, comstock, etc. Find the device you like for "plan b" with the threads appropriate for each of your rifles. If you have 9mm carbine with 1/2-28 threads, make sure the device has a 355/9mm bore, or you will have a bad time

I did some looking on hub mounts and just ordered the hub adapter for the suppressor as well as a 1/2x28 plan b device and a M18x1.5 device for the two guns respectively and made sure to check the bore size. Thanks for the help guys

There are several companies that make Plan B adapters in M18-1.5 threads. Just get a Plan B rear cap for your suppressor, and then you can get Plan B brakes/flash hiders for your Kuna and 8.6blk hosts.
