28 gauge Choke thread

[runngun]

Can anyone please tell me what thread pattern this is? The gun is a model 600 Charles Daly 28 gauge. I tried a Benelli/Beretta Mobil choke and it doesn't fit. I have Googled and can't get a straight answer? Thanks in advance.

Have a good one

Hmmm. That's an acme thread but longer than the mobil choke threads. Akkar makes that gun. Same chokes are on www.gunpartscorp.com.

Yeah these are factory chokes, I  have full, modified and improved cylinder.  Was hoping to find a Turkey choke for it.

Looks like Remington Pro bore. Briley makes an extended choke and pure gold has on as well.

Call Briley. They are awesome
