The team was teasing the release for the past week, despite leaks already showing off what the uniform would be.
This is now the second straight year the Bills revealed an alternate, with their 'cold front' all-white uniforms as part of the NFL Rivalries program that were released last season.
The 'Nickel City' alternates will break ground in the team's new stadium that they'll be playing in this season and onward. Buffalo haven't revealed yet which games the Nickel City uniforms will be worn for.
During the leaks, fans across social media were bashing the new look, with some calling the all-grey look 'one of the worst' in NFL history. The new helmet also marks the fourth helmet logo design since the team became a team in 1959.
It also marks the first time in the team's history that they will be donning a blue helmet.
But Buffalo fans, and fans around the league, aren't holding back their criticism for the new uniforms, as the new is widely known to have some of the best in the NFL.
