Anyone provide the thread size etc. I've got one inbound that needs a new bead. Thanks. PS. This is the vent rib model if that makes a difference.

Must have been a harder question them I thought. What size beads did the early Citori take?

Benelli All 2.6mm
Beretta All 2.6mm
Browning All 3mm
Browning Citori (Older) 3/56
Charles Daly All 3mm (Miroku mostly uses 3mm but some 2.6 mm) Hopefully 3 mm refers to the c. 1960s - 70s Charles Daly guns
EAA - Baikal All 6/48
Fabarm All 3mm
Franchi Semi-Auto 3mm
H & K All 3mm
Hastings Shotgun 3/56

* The Remington 870 have pressed beads and must be tapped first.

Must be a thing with 20ga 500s, Tom. The one on mine went missing 5 or 6 years ago and I have yet to bother replacing it... I'm not Al.😉

Assume the gun finally arrived at your FFL?

Not yet. The auction house told me they would ship 7 to 14 days after payment. I sent them a note yesterday and they repeated 7 to 14 days after payment (cut and paste). I paid for it on the 14th of June via credit card to include shipping.

There is a guy in AZ who probably still advertises on GunBroker. He has/had a huge trove of Miroku parts, and would know what you need. Might even have the correct bead.
