I lucked into some new old stored .504 barrel blanks by Criterion, found them in a garage. bought out of the sale when White Systems went under. They are 20 years old but in perfect condition. Criterion made the best barrels White ever used so these were a real find.
You are seeing the beginnings of a new Custom Bison , the barrel trimmed to one inch diameter, 24 inches long , 504 caliber, with a new custom stock in tough maple, designed specifically for use with a scope. We will install new but old stored original parts to complete the action. The trigger will be by Timney, same as on a Mauser bolt rifle, adjustable for weight of pull. The rifle will finish drilled and tapped for scope and peep bases. but no barrel sights included except on custom order at extra cost since everyone usually mounts a scope. Black Dur-Coat finish on both barreled action and stock. Price is $800 for the basic rifle plus whatever extras you might want and S&H.
Since the gun is custom, you can have any barrel length you want shorter
than 25 inches, any color Dura-coat you want, even pink for your lady,
any length pull shorter than 14.5 inches, front and rear open sights
(but you have to specify exactly what sight you want), a rear mounted
Lyman 57A totally adjustable peep or scope bases and rings, all at extra cost.
