APS CAM870 barrel diameter

[Pikok123]

I would like to built double barrel ASG shotgun using as ammo APS shells which I have.

 

Unfortunetly I can't find information about inner diameter of APS CAM870 barrel. Outer diameter is available but in my case it isn't helpfull.

 

I can experiment with diameter but better use the same value like in original replica.

 

I will be grateful  to provide this information by person who have access to APS CAM870.

Inner diameter of the barrel at muzzle end is 17.3mm

Inner diameter of the barrel at the breach end is 19.5mm

 

Gun used was an APS CAM 870 SAI MKI using MKi shells.

do you mean inside the CAM shells as if looking into them?

 

If this is what you mean then 17mm.

 

If you want free WADs you'll need a 17 or 18mm hold punch.
