Compatibility & Fitment Notes

• Compatible with most mil-spec and commercial AR-15 lower receivers.

• Works with standard mil-spec buffer tubes, bolt carrier groups (BCGs), and upper receivers.

• If you own a precision or highly proprietary receiver, minor fitting may be required—confirm dimensions before final assembly.

Installation Tips (Quick Guide)

1. Safety First: Ensure the firearm is unloaded and the workspace is clear.

2. Tools: Use a roll-pin punch set, small hammer, vise block, and proper armorer’s tools to avoid marring pins or receivers.

3. Order of Assembly: Install takedown/pivot pins and detents, bolt catch, safety selector and detent, trigger/disconnector/hammer group, mag catch, trigger guard and pistol grip, then buffer retainer.

4. Function Check: After assembly perform safety selector, trigger reset, and dry-fire checks. Confirm magazine latch and bolt catch function before live fire.

5. Final Verification: Conduct a supervised live-fire check at the range to validate cycling and reliability. If unsure, consult a qualified gunsmith.

Maintenance & Care

• Inspect springs and pins during regular service intervals.
