SUREFIRE SOCOM SUPPRESSOR ADAPTERINSTALLATION INSTRUCTIONS

USER MANUAL

THIS USER MANUAL HAS BEEN APPROVED FOR PUBLIC RELEASE BY THE DEFENSE OFFICE OF PREPUBLICATION AND SECURITY REVIEW

INSTALLATION INSTRUCTIONS

INCLUDED IN PACKAGING REQUIRED TOOLS

Note: This process is critical to ensure proper installation and funtion of all suppressor adapters that require shims and/or spacers. Beveled spacer with chamfered inside diameter must always be used to ensure proper adapter alignment if included with shim kit. Always use spacer with chamfer facing barrel shoulder before installing other shims, as required, when timing a suppressor adapter to a barrel with a 90-degree shoulder behind threads.

To adjust location and timing of the suppressor indexing tab on the suppressor adapter to bottom dead center (BDC). A combination of shims may be required to properly time the suppressor indexing tab to BDC.

1. Per manufacturer’s specifications, remove existing flash hider/muzzle brake, spacers, shims and/or washers from host weapon. DO NOT reuse factory shims, spacers or washers removed from host weapon.

2. Apply acetone/degreaser to threads on muzzle end of host weapon barrel. Use cleaning cloth and/or brass brush to remove all debris and residue from threads. Additionally apply acetone/degreaser on cotton swab to remove debris from internal threads of adapter. Rocksett will not adhere to threads if surface is not dry and stripped clean of debris and residue.

3. Refer to Timing Wheel Charts, starting on page 6, for appropriate shim stack recommendation.

4. Refer to Figure 1 for proper shim placement and installation.

WARCOMP-556-1/2-28 can be clocked to accommodate improved recoil mitigation for right–or left–handed shooters with the option of neutral timing.

Note: Suppressor locates on indexing tab, which may no longer be at BDC.Clocking of suppressor does not reduce performance of weapon system.

Note: When timing an adapter on end of barrel, drop appropriate shims into adapter and ensure shims lie flat. point muzzle of weapon down before screwing adapter with inserted shims on to barrel threads.

DRY FIT RECOMMENDATIONS FOR BEST TIMING • Place beveled spacer (if included) with intended shim stack chosen from corresponding timing wheel. Note: For best fit place thinner shim toward middle of stack when applicable.

• Install adapter to hand-tight indexing tab to approximately 15 degrees (ie 5:30 position) out of BDC.

• Apply no less than 20 and no more than 30 lb.-ft. of torque (or 2.77 to 4.15 metric kilograms).

• If intending for BDC (ie 6:00 position) dry fit timing is correct. Note: if not in proper timing, remove adapter and add or subtract necessary shims; reinstall to check correctness.

• Remove adapter, shim stack and spacer. Proceed to Step 5 on page 4.

CHAMFERED SPACER

Note: With SCAR-H, use supplied spacer with chamfer facing away from shoulder. Note: MK48 and M240 shims are placed against muzzle face.

Recommended: Use spacer 71348-1 for barrels with under .620” diameter shoulder (sold separately).

5. Apply a thin coat of Rocksett on to suppressor adapter threads and barrel threads. To review material safety data sheet for Rocksett, go to:

www.flexbar.com/PDF/MSDS-Certs/ROCKSETT%20MSDS.pdf

6. Place beveled spacer with intended shim stack chosen from corresponding timing wheel. Note: For best fit place thinner shim toward middle of stack when applicable.

7. Install adapter to hand-tight indexing tab to approximately 15 degrees (ie 5:30 position) out of BDC.

8. Torque suppressor adapter to no less than 20 and no more than 30 lb.-ft. of torque (or 2.77 to 4.15 metric kilograms). To tighten suppressor adapter onto barrel threads, use a torque wrench and open-ended crow’s foot, armorer’s tool or pronged adapter wrench. When suppressor index pin notch on adapter is BDC.

9. Allow Rocksett to cure for 24 hours before firing host weapon.
