Compatibility

Triggers

  • Use AR triggers with full power hammer springs.
  • The MP5 bolt carrier compresses the AR style hammer slightly more than an AR bolt carrier. Many two-stage triggers like Geisseles do not have the same range of motion, and are not compatible.
  • Drop in triggers with sloped cassettes like the Rise Armament RA-240, Timney Competition, JP FC-M will fit in the housing. 
  • Drop in triggers with tall cassettes like Timney Impact and PCC, Triggertech, Rise Armament RA-434 Rave PCC Rave 140, Midwest Industries Drop in, and CMC will not fit.
  • Mil-spec, and other AR triggers that do not have a cassette will fit.

Grips

  • The Sporting Trigger Group has a different contour than the standard AR lower.
  • A2, Magpul MOE-K, Daniel Defense, and Griffin Armament A3 pistol grips will work.
  • Any Pistol Grip with a Backstrap tang that extends higher than the Pistol Grip’s mounting surface, will not fit. Examples include Magpul MOE, B5, Wilson Combat, HK V2.

Safety

  • Most AR Safety levers are compatible with the Sporting Trigger Group.
  • The Housing’s Ejection Lever Pin features prevent a safety from rotating a complete 180 degrees.
  • Ambidextrous safeties with a tall indicating point may make contact with the top of the Trigger Group.
