I was looking at some of the rifles at this years SB Nationals. I was intrigued with the barrel weights that were on a silver stocked Anschutz that one of the Mexicans was shooting. Does someone make these weights and sell them or are they made on a purely custom basis?

Most of those are made by a gunsmith/machinist for the particular rifle barrrel dia. and weight/balance the shooter wants to achive.

Any gusmith/machinist would probably make them for you to your specifications.
