Charles Daly barrel bead
 

My son has a Charles Daly semi-auto Ducks Unlimited gun. It looks like a Field Hunter model. He lost the bead at the end of the barrel yesterday while shooting sporting clays. Does anyone know what the thread size is on this gun? Would a Remington thread fit this gun? They use the same chokes.

It's 3mm x .05mm

I would drill it out and tap it for 6-48. Take a #31 drill bit and drill out the hole and then get a 6-48 bottom tap and tap the hole. I will only take you about a minute to do and if you do this you will be able to find a bead to fit any where in the world.

No but if you tap it for 6-48 it will.

Thanks for the info
