From 1968-1978, the New York Rifle, Pistol and Shotgun Club was located at the Armory where it featured a multi-lane, 100 yard indoor shooting range, run by Barry Satz who lived a few blocks away.

The club met every Tuesday night and members brought myriad types of small arms from around the city to shoot at the range's targets.

[7] In 2002, the armory was chosen as the permanent home of the National Track and Field Hall of Fame,[10] and it is now the largest site of indoor college and high school invitationals in the world.

First held in 1908, the Millrose Games is the centerpiece of The Armory’s track and field calendar, and is arguably the most prestigious indoor meet in the world.

Millrose features elite competition at every level, with youth, high school, collegiate, professional, and masters races.

Millrose traditionally concludes with the Wanamaker Mile, which has featured many icons of the sport, including Eamonn Coghlan and Bernard Lagat.

Students from Armory College Prep have gone on to attend Cornell, Amherst, Haverford, Williams, Washington & Lee, and many other competitive institutions.

ACP works to close the opportunity gap for the students by providing one-on-one tutoring in a variety of subjects, focusing on Math and English.
