UNLV (19-7, 8-5 Mountain West Conference) has won five of its last six games. Air Force (10-14, 4-8) had its two-game win streak snapped.
The Falcons pulled to 65-64 with 3:33 to play, but McCoy answered with a dunk and Mooring a 3-pointer to spark a 16-9 surge to seal it for UNLV.
Mooring was 7 of 12 from the floor and made five 3-pointers. Jordan Johnson and Tervell Beck added 16 points apiece for the Runnin' Rebels, who made 9 of 17 (53 percent) from long range and outrebounded Air Force 52-25.
UNLV opened the game on a 23-8 run, led 31-25 at halftime and never trailed after Air Force made the opening bucket.
