REVIEW YOUR MUZZLE DEVICE OR SUPPRESSOR MOUNT INSTRUCTIONS TO CONFIRM THE CORRECT ALIGNMENT POINT.
USE HEAT-RESISTANT THREAD-LOCKER, ALWAYS VERIFY CONCENTRICITY BY USING AN ALIGNMENT ROD, AND DO NOT EXCEED 25 FT. LB. OF TORQUE.
DIRECT THREAD SILENCER RETENTION:
FOLLOW STEPS 1-6 OF THE FOLLOWING INSTRUCTIONS. THREAD YOUR SILENCER ONTO THE BARREL ENSURING THE WASHERS REMAIN IN CONFIGURATION. TORQUE TO 3-5 FT. LB. AND VERIFY CONCENTRICITY. CHECK THE TIGHTNESS OF YOUR DIRECT THREAD SILENCER BEFORE EACH SHOOTING SESSION AND PERIODICALLY DURING EXTENDED USE.
1. SECURE THE UPPER RECEIVER IN A BENCH VISE. ENSURE ALL THREADS ARE CLEAN..
2. THE TIMING WASHER HAS ALTERNATING HEIGHTS, THESE ARE SHOWN IN YELLOW/PINK IN OUR DIAGRAMS FOR EASE OF DIFFERENTIATION.
3. PLACE THE BACKING WASHER ON THE BARREL SO THE FLAT SIDE IS FACING OUT. THIS ACTS AS A SUPPORT FOR THE BASE WASHER.
4. PLACE THE BASE WASHER ON THE BARREL WITH THE RAISED SECTIONS FACING OUT.
5. PLACE THE TIMING WASHER ON THE BARREL WITH THE RAISED SECTIONS FACING THE BASE WASHER.
6. ALIGN THE WASHERS SO THAT THE RAISED SECTIONS OF THE BASE WASHER ARE ALIGNED WITH THE RAISED SPACES OF THE TIMING WASHER (YELLOW IN DIAGRAM) SHOWN IN CONFIGURATION A.
IN THIS CONFIGURATION, THE WASHER SET SHOULD MEASURE 0.2175”.
7. HAND TIGHTEN YOUR MUZZLE DEVICE ONTO THE BARREL ENSURING THE WASHERS REMAIN IN CONFIGURATION A.
8. DETERMINE THE 12 O’CLOCK POSITION (TOP/CENTER) OF BARREL AND CHECK THE ALIGNMENT POINT OF YOUR MUZZLE DEVICE BASED ON THE MANUFACTURER’S SPECIFICATIONS.
IF THE MUZZLE DEVICE ALIGNMENT POINT FALLS BETWEEN 3 AND 9 O’CLOCK (BOTTOM HALF OF THE BARREL), PROCEED TO STEP 10.
9. IF THE MUZZLE DEVICE ALIGNMENT POINT IS BETWEEN 9 AND 3 O’CLOCK (TOP HALF OF BARREL) WHEN HAND-TIGHT, LOOSEN THE MUZZLE DEVICE UNTIL YOU CAN ACCESS THE TOP WASHER.
ROTATE THE TIMING WASHER SO THE RAISED SECTIONS OF THE BASE WASHER ALIGN WITH THE RECESSED SECTIONS OF THE TIMING WASHER (PINK IN DIAGRAM).
IN THIS CONFIGURATION, THE WASHER SET SHOULD MEASURE 0.20” AND THE ALIGNMENT POINT SHOULD NOW FALL BETWEEN 3 AND 9 O’CLOCK.
10. APPLY HEAT-RESISTANT THREAD LOCKER TO THE BARREL THREADS, THEN TORQUE THE MUZZLE DEVICE ENSURING ALIGNMENT PER THE MANUFACTURER’S SPECIFICATIONS.
ONCE THE ALIGNMENT POINT IS PROPERLY ORIENTED, YOUR INSTALLATION IS COMPLETE.
DO NOT TORQUE PAST THE ALIGNMENT POINT—NO ADDITIONAL TIGHTENING IS NEEDED, AS THE STD WAS DESIGNED TO PRODUCE 25 FT. LB. OF PRESSURE.
