Is this the Vice in Question?
These Deluxe Barrel Vises are made by our friend Bob "The Viper" Pastor. Machined from 6061 aluminum and finished with a durable, baked on, non-slip powdercoat, these deluxe barrel vises feature the usual hardened bolts and nuts along with fully captured return spings. The return springs prevent the top of the vise from flopping around, making inserting and removing barrels from the vise much quicker and easier. This feature along with the powdercoat finish protects the finish of your barrels from scratches and most importantly protects the crown of the muzzle. You will not find a higher quality barrel vise with these features anywhere.
