Key Installation Tips

• Take Your Time: Small parts require patience. Rushing leads to lost parts and scratched receivers.
• Pin Alignment is Critical: Line up holes carefully before driving pins. Misalignment can damage your lower receiver.
• Spring Tension Matters: Many parts are under spring tension. Control them carefully during installation.
• Test Function: Check each component’s operation before moving to the next step.

Troubleshooting Common Issues

• Stuck Pins: Use proper punch size. Too small creates slippage. Too large damages pins.
• Lost Detents: Work over a towel or in a contained area. Keep spare detents handy. The RISE OH S#IT KIT is the perfect solution if you want to keep spare detents, springs, etc. on hand.

Final Function Check

Before calling it complete:

• Test magazine insertion and release with RISE Magazine Release Button.
• Verify RISE Ambidextrous Safety Selector engages properly:
  • Flip it to the safe position and squeeze the trigger to ensure it does not fire on safe.
  • Flip it to the fire position and squeeze the trigger to ensure proper trigger function.
    • Repeat this process 3-5 times to ensure safety is installed and functioning correctly.
• Check Enhanced Takedown & Pivot Pin operation; punch pins out and back in to ensure smooth operation.
