Ring of Honor (2017-present)
Milonas was a part of the 2017 ROH Top Prospect Tournament, an annual tournament hosted by Ring of Honor where the winner gets a Ring of Honor contract and a future shot at the ROH World Television Championship. He defeated Raphael King in the first round of the tournament but was defeated in the semifinals by Josh Woods at ROH Manhattan Mayhem 2017 in a dark match.
In 2018, Milonas began teaming with Silas Young and The Beer City Bruiser. The heel trio did not find much success outside of Silas Young's Television Championship reigns. Eventually, on the 367th episode of ROH TV, Silas Young walked out on his teammates during a 6-man Tag Team Championship match against Bullet Club (Cody & The Young Bucks). With Silas leaving, Milonas and Bruiser remained a team now calling themselves The Bouncers.
On February 5, 2019, it was announced that Brian Milonas signed a full time contract with Ring of Honor. The Bouncers won multipe matches mainly against enhancement talent. At ROH Bound By Honor 2019, The Bouncers and Coast 2 Coast were defeated by Lifeblood (Bandido, Juice Robinson, Mark Haskins & Tracy Williams). At ROH-NJPW G1 Supercard 2019, Milonas & Bruiser participated in the Honor Rumble but neither of them were able to win. Milonas was notably eliminated by Jushin Liger.
In June 2019 The Bouncers began aiming higher as they set their sights on the ROH World Tag Team Championship. At ROH State of the Art day 2, The Bouncers won a Gauntlet match to determine the #1 Contenders for the World Tag Team championships. At ROH Mass Hysteria 2019 The Briscoes (Mark Briscoe & Jay Briscoe) successfully defended their World Tag Team titles against The Bouncers.
