Is this an Autococker threaded barrel?

[staf0s]

Sorry if it’s hard to tell. Not even sure if you’re able to tell me from just looking. It looks like it has 4-5 threads. All the AC barrels online look like that have 5 threads, my ANS barrel has 11 threads. I understand the pitch of the threads is what matters. Thanks for any help!

My first guess would be spyder
