The Professional in duty Military/Law Enforcement Carbine Conversion Kit [CCK].

The HERA ARMS Triarii Stock System converts pistols [duty side-arms] into accurate CQB/CQC assault rifles in less than 4 seconds – just drop in, slide, lock and go.

Deployed by Spec-Ops, Rapid Response Units [RRU], Crises Response Teams [CRT], patrol units and other first on scene law enforcement units around the globe, whose operational theaters are instant CQB/CQC, gun battles, shootouts, etc. the HERA ARMS Triarii has been designed to meet the functions and needs of an instant side-arm upgrade for:

  • Drastically improves accuracy hence enabling more successful engagement/return fire at much greater lengths.
  • Preconfigured with a wealth of sights and optics thanks to the four mil-spec rails.
  • Perfectly sized and balanced for tactical entries, searches with the additions of flashlights, glass breakers, striking devices, etc.
  • No need of extra Command and Control as the HERA ARMS Triarii Stock System is not classified as a firearm, hence it can be kept with the vehicle, without the need to remove and place in a strong room.
  • Caliber independent
  • Provides logistical advantages as it uses the already available side-arm.

Be it law enforcement/military, agency or sport users, the HERA ARMS Triarii Stock System provides the needed time to any situation.
