Includes:

  • M4E1 Lower Receiver
  • M4E1 Threaded Assembled Upper Receiver, No Forward Assist Provision
  • ATLAS R-ONE or S-ONE 15" Handguard
  • All 3 pieces are finished in mil-spec Anodized Black

M4E1 Lower Receiver Features:

  • Threaded Bolt Catch Roll Pin - Allows for simple installation of the bolt catch and virtually eliminates the chance to damage the finish during installation (pin included).
  • Integrated Trigger Guard - Eliminates the possibility of breaking the trigger guard tabs by integrating the trigger guard into the lower, creating a stronger more rigid platform to build upon.
  • Upper Tension Screw - Allows users to fine tune the fit of the upper and lower receiver using a nylon tipped tensioning set screw inserted in the grip tang of the lower receiver. This provides a tight fit with any standard AR15 upper receiver.
  • Threaded Takedown Pin Detent Recess - Allows user to easily install the Takedown Pin detent and spring with the use of a 4-40 set screw (no more launching detents across the room).
