I've found two so far, a Surefire and Dead Air Odessa. Are there any others? This is for a PCC and the rail is 1.3" inside so I need to find all the small cans that will fit. This is a dedicated install.
1/2x36 threads too.
 
I went Form 1 when I needed something similar.

Thompson Machine Poseidon is another 1.25” option. It is available in 1/2-36.
 
AAC Evolution was 1.25”, but you’d need to find a used one or a demo model somebody still had. It’s probably the quietest option of that diameter.

And just so you don’t run into the same issue I did. Is it a PSA 9mm Upper by chance?
 
Add on question. If I don't see a 1/2-36 thread option, are the $20 adaptors you see online acceptable solutions?

Nope. Foxtrot Mike. I can't change the hand guard because it's a forward/side charger and there a trolly and op rod in the hand guard. 8.5" barrel and 10" hand guard.

To go 1/2-36 to 1/2-28? I used one on my AR-9 for awhile. I also used a 1/2-28 to 1/2-28 (the new male threads were shorter and had o-ring engagement for my Spectre II) on my AR-57. Both were Silencerco brand.

Adapters can lead to tolerance stacking issues, but some are well made and work fine.

Cool. My PSA one was 1.34”...but only for the first inch or so. It was actually smaller (due to being square) the rest of the way and I had the inside of the rail bored out.
