HANDGUARD INSTALLATION

Step 6 – Install RPP Barrel Band

Orient the barrel band correctly:

• Threaded adjustment hole faces upward.
• Set screw aligns with the barrel groove.

1. Slide the barrel band onto the barrel.
2. Align the set screw with the barrel groove.
3. Install the supplied set screw.
4. Tighten lightly.

IMPORTANT

Do not overtighten.

The barrel band is designed to accommodate variations in barrel diameter.

A small amount of movement is normal at this stage.

Step 7 – Install Handguard

1. Position the handguard onto the rifle.
2. Insert the rear flange into the receiver.
3. Ensure the handguard is fully seated.

Step 8 – Install Barrel Band Mounting Screws

1. Align the handguard with the barrel band.
2. Install the supplied mounting screws through the handguard into the barrel band.
3. Leave slightly loose for final alignment.

IMPORTANT

Do not fully tighten at this stage.

Step 9 – Reinstall Magazine Tube

2. Ensure the magazine tube is properly indexed.
3. Reinstall the front barrel band.

NOTE

The magazine tube and barrel grooves must align correctly before installing hardware.

Step 10 – Reinstall Magazine Spring and End Cap

1. Reinstall the magazine spring.
2. Compress the spring carefully.

Step 11 – Install Upper Barrel Band Screw

1. Install the upper barrel band screw.
2. Torque to 6in/lbs.

IMPORTANT

Do not overtighten the upper barrel band screw.

The barrel band is designed to accommodate variations in barrel diameter between manufacturers and production runs.

The upper screw secures the barrel band while the rear alignment set screws stabilize the handguard.

Step 12 – Install Rear Alignment Set Screws

1. Install the rear alignment set screws.
2. Tighten until they lightly contact the barrel.

IMPORTANT

• Do not overtighten.
• Hand tight only.

FINAL ALIGNMENT

Step 13 – Center Handguard

Visually inspect the gap between the handguard and barrel.

Adjust until:

• Both sides appear even.
• The handguard sits parallel to the barrel.
• The magazine tube remains properly aligned.

Step 14 – Final Tightening

After confirming alignment:

• Barrel Band Mounting Screws: 6 in-lbs
• Upper Barrel Band Screw: 6 in-lbs
• Alignment Set Screws: Hand Tight Only

IMPORTANT

• Set screws should only lightly contact the barrel.
• Do not apply additional torque after barrel contact is achieved.
• Allow thread locker to cure before firing.

MAS & Gator Rail Installation

The MAS system utilizes one or two Gator Rails mounted to the top of the handguard.

Step 15 – Position Gator Rail

1. Determine the desired Gator Rail location.
2. Place the Gator Rail into the mounting pocket on top of the handguard.
3. Verify orientation before installing hardware.

NOTE

• Most users will orient the Gator Rail toward the muzzle.
• A second Gator Rail may be installed in the forward position if desired.

Step 16 – Install Gator Rail Mounting Screws

1. Position the Gator Rail onto the handguard.
2. Install the four supplied large-head mounting screws.
3. Start all screws by hand.
4. Verify the Gator Rail sits flush against the handguard.

IMPORTANT

• Do not cross-thread the screws.
• Test fit all hardware before applying thread locker.

Recommended

1. Install all four screws dry.
2. Verify proper fitment.
3. Remove one screw at a time.
4. Apply Blue or Purple Loctite.
5. Reinstall the screw.

Step 17 – Install Jack Screws

The four jack screws install directly behind the mounting screws.

1. Install all four jack screws.
2. Tighten until they lightly contact the handguard mounting surface.

IMPORTANT

Do not overtighten.

The mounting screws and jack screws work against one another to securely clamp the Gator Rail to the handguard.

Step 18 – Final Tightening

After confirming alignment:

• Gator Rail Mounting Screws — Hand Tight
• Jack Screws — Hand Tight

IMPORTANT

• Apply Blue or Purple Loctite to the mounting screws.
• Do not overtighten.
