INSTALLATION INSTRUCTIONS

• Make sure all threads are clean of grease, carbon, and loctite. Wipe the threads down till they're clean. If the threads are not cleaned, the loctite will not set properly.
• Only use loctite 243 on the barrel AND set screw threads. Some versions of the blue Loctite are not very strong and will not hold up. Feel free to use a generous amount.
• Torque the set screws to no more than 18in/lbs for 8-32 set screws and no more than 11in/lbs for 6-32 set screws. 
• Allow the loctite to set for 24-48 hours before using.
• Please be sure that the compensator is not touching the slide, frame, or guide rod as that can cause cycling issues.
