Got a used rifle that was said to have asr Mount. I was excited, but got it and it is certainly not an asr Mount. Or anything else I'm familiar with. Appears to be a thread behind taper system like Plan B and based on my measurements the pitch is 1"x24tpi. Pics attached - anyone know who makes this brake (looks kind of interesting with tradition design plus top port) and what mounting platform this is for??
What muzzle brake/suppressor mount is this?

Those look like Dead Air Key-mo brakes or one of their other styles. That doesn't mean they are though.
None of them look like what Q sells but 24tpi is the thread pitch of an 8.6BLK barrel. Dead Air sells this (KeyMicro):

Dead Air's DA-108, Key-Mo btw, has 3/4" x 24 tpi threads
Surely that's not the only offerings for 3/4 - 24tpi
3/4" threads are a shade over 1" in diameter btw. Like 1.050"

3/4" inside threads on your link for the muzzle diameter. The keymo system is not externally threaded in any standard pattern, 3/4" or otherwise. So the gun would be male threaded 3/4x24, the muzzle device female threaded 3/4x24 (in this case) but my device is externally male threaded 1"x24. Standard 5/8x24 inside for the barrel which doesn't tell us anything…
That being said I am curious about your comment on 3/4" threads being 1.050" in diameter, please explain that?

Google... but I missed that it was pipe threads (MNPT). I don't think a suppressor uses pipe threads lol
"A 3/4" NPT pipe thread has an outside diameter -OD - of 1.050 inches."
Female threads. I missed that too. Some of the devices on Q's site (8.6BLK) are female (I have a couple) of them. The device is female on the barrel side, to male threads to mate to the can, which is female.
I didn't see anything on Q's site that matches your photos. This is a real head scratcher.

Yeah it is… got this question on a couple forums and haven't found an answer yet, really surprising! May have to take it to a shop with cans and see if they'll let me try a few fittings, or see if the previous owner can put me in touch with the gunsmith who built the rig and get an answer. Or just put it on the shelf of misfit pieces, throw on an asr brake and call it a day.
I did shoot it today for the first time, it was amazing at taming the gun! I have no baseline as I've only shot it with this brake - and only twice to get it on paper at 100, but Never lost my sight picture, felt like a well set up 223. Wondering if my silencerco brake will be as effective?
