Performance You Can Feel

• Secure Lockup: The castle nut & end plate interface keeps the extension torqued and staked correctly to withstand heavy use.

• Sling-Ready Options: If your end plate includes a QD socket, you’ll gain fast, ambidextrous sling mounting without extra hardware.

• Caliber Range: Suitable for typical AR-15 calibers (5.56/.223, .300 BLK, etc.); buffer weight tuning may be required for specialized setups.

Installation Overview (High-Level)

1. Safety First: Ensure the firearm is unloaded; remove bolt carrier group and magazine.

2. Prep the Lower: Install the buffer retainer and spring; hold in place while threading the receiver extension.

3. End Plate & Castle Nut: Slide onto the tube, align takedown detent spring, then torque the castle nut to spec.

4. Stake the Castle Nut: Stake at least once into the castle nut notch to prevent backing out under recoil.

5. Function Check: Verify takedown pin spring tension, buffer retention, and stock fit before live fire.

Best Practices & Tuning

• Buffer Weight: Start with a standard carbine buffer; consider H/H2 weights if you experience over-gassing or want a slower impulse.

• Gas System: Ensure your gas block is aligned and the gas port is appropriate for your barrel length and ammo.

• Lubrication: Lightly lube the action spring and inside of the tube for quiet, smooth cycling.

Care & Maintenance

• Finish Care: Wipe anodized parts with a soft cloth; avoid harsh abrasives or steel tools that could mar the color.

• Fastener Checks: Recheck castle nut torque and staking after your first range session.

• Spring Health: Replace action springs periodically to maintain consistent cycling.
