TROY specifically designed the M5 for the 9mm caliber and the popular Glock® magazine. The M5 is not a simple conversion, it was engineered from the ground up and offers a sharp, clean profile. The lower receiver‘s magazine well has been reduced in size and contoured to the angle of the Glock magazine allowing dependable reliability for feeding and extraction. It does not require an adapter.
By utilizing the TROY M-LOK® BattleRail and by removing unnecessary items like the forward assist, the upper receiver is incredibly light-weight. The ejection port has been resized for the 9mm cartridge and includes a built-in shell deflector.
