The CMP store also has criterion barrels in stock usually. Along with some years of military take offs for those restoring a garand. Not as much in the stores as there used to be now. I can remember when it was back in erie ordance a small office with a huge wharehouse. Filled out the order slip and waited for them to bring it up. Parts kits for various military guns, stocks, garands and tools. I got lucky after a match and got a timing block for the garand.
