I recently joined the ranks of suppressor owners with a SiCo Omega 30 cal. It's primary use is on my 6.5 Creedmoor and the first trip to the range was a big success. For the time I'm going with a direct thread attachment method.

I'd also like to suppress my 223 Rem varmint rifle. I know the best solution would be to thread the muzzle to 1/2-28 and get another suppressor. But from a cost and time perspective that's just not in the cards for now. So how about an adapter for 1/2-28 to 5/8-24 and then be able to use my Omega on the 223? Has anyone used this method to put a suppressor on a .22 cal rifle? Brownells carries a couple of models and the one from Trousa for $59 looks like a quality piece. Anyone have a recommendation?

And what about getting an adapter for my AR? It's muzzle is already threaded. Would I see some benefit using the Omega on it?

Thanks in advance.
 
You just need the 1/2x28 Direct Thread Mount for the Omega from Silencerco. The mount just unscrews from the back of the can using the included wrench. You just switch the mount for each use.

Or, buy the 1/2x28 ASR brake and use the ASR mount on the can. If both rifles have the ASR, then it’s a simple swap and no changing parts. I have the ASR on several rifles, including ARs and just move the Omega around as desired.

You can find them cheaper at other online retailers.

This is the solution. You already have a modular can system - utilize it, and don’t add more interfaces that are possible sources of mis-alignment or failure.
 
Why not just thread it 5/8-24?

I own a SiCo Omega 30. Every rifle I have, minus an AR (which has the ASR brake on it) is threaded 5/8-24. I have run my Omega (direct thread) on a 308 bolt gun, 6.5 bolt gun, 223 bolt gun and a 224 valkyrie AR.

Zero issues.

I thought about just having the 223 threaded to 5/8-24. It just seems that 1/2-28 is more of the "standard" thread pattern for 22 Cal rifles. I'm probably guilty of over thinking this.
 
Thanks for the responses. I have several options and I just need to pick one. Bottom line is that my Omega will be able to suppress the 223 like I want it to.
 
If you can, thread the barrel 5/8x24, no reason to do 1/2x28 if you don't have to. A thread adapter should be the absolute last resort. We have SilencerCo muzzle brakes and flash hiders at some the best prices I think.

This is where Ive gotten all my asr mounts the last couple years. The best price youll find new and free shipping.

Going with direct thread and adapters is like pushing your car up a hill instead of driving it.
The can with the asr module will mount on all these brakes no matter what the barrel is threaded.

I have used the 1/2"-28 to 5/8"-24 adaptors and they work great just if you leave it in the can for to long you could have problems getting it back out of the can depending on the material the adaptor is made from. Lets just say I have done that and its a pain in the ass getting it out. I would just buy the brakes and run them that way your threads are protected all the time and you are not have to constantly keep track of the little adaptor.
