A company called Cerus Riflestocks makes very unique bolt-action rifle stocks. What sets them apart is that they use different types of woods and carbon fiber layers epoxied together to make sort of custom laminate stocks.
The company is mostly specialized in competition rifle (F-Class) stock making. They claim to be able to make them with virtually any combination of hardwood. To bond the different wood layers together they use epoxies used in naval and airspace industries. The stocks are made on 4-axis CNC machines.
The Cerus stocks are not completely drop-in ones and will require some inletting for parts like the bolt release and bolt handle. Typically, these stocks are used with custom Remington 700 actions such as those made by BAT Machine, Borden Accuracy, Stiller’s Precision Firearms, Defiance Machine, Pierce Engineering etc. The Cerus stocks are also compatible with virtually any barrel contour up to 1.25″ straight cylinder.
Depending on the wood types, the weights of the same profile stocks may differ. The prices for Cerus stocks vary roughly from $750 to $1100.
The advantage of these stocks is probably the use of different properties of woods and carbon fiber in the areas where they are most needed. I think this method can also be used to make stocks with a thin outer layer of some exotic woods that are not suitable (too soft or brittle or whatever other reason) to be a rifle stock but have a beautiful grain and color. That way you’ll still have a strong hardwood stock in the core and an unusual new appearance.
