The reason for a muzzle brake on a .223 rilfe is to allow the shooter to see the bullet impact. This can be extremely valuable for a varmint hunter shooting alone so he can correct for misses at extreme range - I know it works well on a .22-250. On a Contender a brake is of dubious value, but many shooters just like the looks of a brake. Marketing is about meeting the consumers' perceived needs, not their real needs.
