I've always been happy with the factory stuff.

Factory muzzle brake? I have the flash hider, but never heard of/seen an HK muzzle brake, where can I get one?

My Adult son decades ago left me with a new HK91/93 competition rear sight and I would like to know what it and a couple of new leather slings and a instruction book would be worth for me to sell them.
