Modification of your firearm is required. To ensure proper operation a qualified Gunsmith is recommended for installation.
Tools needed to complete installation include:
• Power Drill
• 5/64" Allen Wrench
• 8-32 Tap
• Aluminum Cutting Fluid (such as WD-40)
• Standard Mil-Spec Mag Catch, Spring and Button
When installed properly in your firearm, the Freedom Fighter blocks the magazine release until the rear pin is removed and the upper receiver is lifted upward and away from the lower receiver.
