Where is a good place to get some vinyl endcaps to protect both ends of a barrel?
I have barrels that have breech diameters from 1.200"- 1.350"
Muzzle diameters from .700"- .950"
Thanks
Try www.caplugs.com They make the plugs and are available many places listed on the web.
McMaster-Carr is always a good choice as mentioned.
Centerfire
Sinclair and Kelbly's have them
