Installation Best Practices
Prep & Protect: Degrease threads; tape the receiver to prevent cosmetic marring during castle-nut work.
Assembly Order: Slide on the castle nut and end plate, capture the rear takedown spring, and install the buffer retainer before final tube indexing.
Torque & Stake: Torque the castle nut to spec and stake the end plate for duty-grade security.
Function Check: Verify smooth buffer travel, correct bolt catch function, and full stock adjustment.
Tuning Tip: If you change gas system length, muzzle device, or ammunition, evaluate ejection pattern and consider alternate buffer weights to fine-tune reliability.

Care & Maintenance
Wipe the anodized tube with a soft cloth after range days.
Use aluminum-safe, non-abrasive cleaners on colored surfaces.
Lightly lube the action spring and inside of the tube; periodically verify castle-nut torque and staking after high round counts.
