Proprietary parts & LPK's

Both the 0940 and 1045 receivers are designed to accept parts from a standard AR-15 mil-spec lower parts kit, minus a few proprietary parts. The proprietary parts will come preinstalled on all complete firearms. Lower receivers and receiver sets will have some proprietary parts installed and some in a small bag for end user assembly.

The proprietary parts include the following:

  • Magazine release lever
  • Magazine release spring
  • Ejector
  • Bolt catch transfer bar
  • Lightened bolt catch spring
  • Bolt catch dowel pin
  • Bolt catch set screw
  • Associated roll pins
