Other Specifications and Features of the American Flag Builder Set:

  • Limited Edition Distressed American Flag Cerakote!

  • Machined from 7075-T6 aircraft grade billet aluminum
  • Precision machined magazine well with beveled feed lip for easy mag swaps
  • Machined to be compatible with 45 and 60 degree short throw fire control selectors such as the BAD_ASS ST 45 Lever
  • Caliber marking of "Multi" so it can be used with different pistol caliber uppers
  • Compatible with most standard AR-15 components and most aftermarket parts
  • Take down pin spring and detent hole is threaded for a 6-32 set screw for easy capturing (hardware included)
  • Upper tension screw behind grip screw (threaded hole with hardware included) to adjust any “slop” out of vertical fit between upper and lower
  • Threaded bolt catch pin (Threaded hole and hardware)
  • Integrated large opening "winter" trigger guard
  • Proprietary aluminum magazine catch assembly and ejector are included
  • Manufactured to MILSPEC (where applicable) on state of the art CNC equipment for consistent quality parts and exacting tolerances
  • Contains integrated Last Round Bolt Hold Open (LRBHO) technology (PATENT PENDING) that reliably holds the bolt open when magazine is empty
  • **NOTE — This upper is not machined for a gas tube as it is intended for blowback gas systems only
  • *Due to the force exerted on the BCG with a blow back system, there is a high likely hood of breaking the bolt catch when activated by the LRBHO feature. New Frontier Armory is not responsible for sending replacements as this is not a warranty issue.

**NOTE – Please read the FAQ below regarding adjustment of your ejector before use and ensure you re-assemble with Loctite or similar thread locker to prevent screws from backing out over time.
