1. SUREFIRE SOUND SUPPRESSOR SYSTEMS
Using SureFire’s expertise in weapon systems, aerospace materials, product testing, and
precision manufacturing, our design team built a best-in-class suppressor that incorporates
all the key features suppressor users have long sought.
Accuracy: Patented Fast-Attach®feature ensures minimal, consistent
point-of-impact shift.
Suppression: Provide consistent sound, flash, and dust signature reduction.
Each suppressor is tested to SureFire’s exacting standards.
Balance: Compact size and light weight allow for minimal impact on
weapon handling.
Durability: High-temp aerospace alloys and precision manufacturing tolerances
provide increased durability, making fulltime suppressor use a reality.
Safety: Constructed using fail-safe baffles that are designed to allow an unbalanced
or defective projectile to pass through the baffles so it continues down range.

6. SUPPRESSOR ATTACHMENT PROCEDURES
1. Depress the latch on lock ring and hold to keep it unlocked.
2. Rotate the lock ring, following the black arrow in Figure 4, to the unlocked position.
3. Slide the suppressor over the adapter following the white arrow in Figure 4. Rotate
counterclockwise until the indexing slot on the suppressor (Figure 5B) lines up with and
seats onto the indexing tab on the adapter (Figure 5A). Ensure that the suppressor is fully
seated onto the adapter.
4. Rotate the lock ring to locked position following the arrow in Figure 6 until it
can no longer be rotated. The lock ring should rotate approximately 180º.
Audible clicks will be heard during this process.
5. SUPPRESSOR ADAPTER INSTALLATION PROCEDURES
Note: Refer to SureFire SOCOM adapter installation instructions
from your adapter purchase or visit www.surefire.com.
Confirm that weapon is unloaded and on SAFE (Refer to the user manual provided
with the weapon for proper weapon safety features and handling instructions)
7. SUPPRESSOR REMOVAL PROCEDURES
1. Depress the latch on lock ring and hold to keep it unlocked.
2. Rotate the lock ring, following the black arrow in Figure 7A, to the unlocked position.
3. Firmly grasp the suppressor tube and pull it away from the host weapon as shown in Figure 7B.

CAUTION: Do not handle suppressor immediately after it has been used in live-fire
operations. Allow suppressor to cool off sufficiently before handling. Surface of the suppressor
and host weapon can reach temperatures that will inflict severe burns if handled immediately
after live-fire operations!
CAUTION: If lock-ring doesn’t rotate approximately 180 º during installation, the suppressor
is not fully seated on adapter. Remove suppressor and repeat steps 3 & 4.

8. FIRING SCHEDULE
Limit full auto firing to reduce heat buildup and extend suppressor life. Avoid firing
more than 90 rounds of sustained fire. If this limit is reached, allow the unit to cool
before resuming fire if possible. High-rate firing beyond 120 rounds can cause cook-
off conditions (clear stoppages quickly and leave the chamber empty).

9. WET SUPPRESSION
To eliminate first round flash, detach suppressor and add a small amount of water into the
rear of the suppressor or submerge suppressor under water. Be sure to drain all excess water
before re-attaching suppressor.
Note: A “wet” suppressor can be used in potentially flammable environments;
it reduces the possibility of a secondary ignition.

10.3 ARMORER LEVEL CLEANING PROCEDURES
Note: Extensive cleaning of the Surefire SOCOM/SOCOM2 suppressor is optional and not required.
1. Place suppressor muzzle down in a container that will hold liquid.
2. Fill container with CLR®cleaner until just below the lock ring.
3. Let the suppressor soak in CLR cleaner undisturbed for 24 hours.
4. Remove the suppressor from the CLR cleaner and rinse with water.
5. Brush the attachment areas of the suppressor with the supplied nylon cleaning brush
to remove any carbon buildup.
6. Rinse the suppressor in clean water after brushing.
7. Fire 5-10 rounds of live ammunition through the suppressor to expel loosened carbon in the
sealed section of the suppressor.
8. Process can be repeated annually or every 10,000 rounds if desired.
10. MAINTENANCE
While SureFire suppressors require minimal maintenance, it is recommended that the adapter
and suppressor be cleaned in conjunction with regular weapon maintenance. Cleaning should
be conducted as often as necessary.
10.1 LUBRICATION
SureFire suppressors are manufactured with a permanent dry lubricant on the lock ring and require no
additional lubrication. Any weapons-grade oil may be used in addition to the dry lubricant to facilitate
smooth rotation of the lock ring.
10.2 FIELD CLEANING PROCEDURES
Note: Suppressor back section must be cleaned prior to attachment if alternating
between different model adapter types. (i.e. alternating between a muzzle brake and a flash hider)
1. Remove suppressor from host weapon by following the suppressor removal procedures.
2. Brush and/or scrape carbon and copper residue from the inside of the suppressor
attachment area.
3. Brush and/or scrape carbon and copper residue from the adapter.
Note: Gun cleaner may be used to remove carbon/copper fouling from both the adapter
and the corresponding internal mounting surfaces of the suppressor.
11. DEMIL PROCEDURES
Silencers/suppressors/mufflers are deemed code “D” items. The preferred method of DEMIL for items
assigned code “D” is smelting. Silencers/suppressors/mufflers shall be demilitarized by smelting,
breaking, shearing, crushing, deep water dumping, or cutting utilizing a cutting tip that minimally
displaces 1/2 inch of metal, or crushed to the extent necessary to preclude restoration to a usable
condition. At least three cuts shall be made with at least one cut through the back section/lock ring area.
The back section/lock ring area cut shall be at least one wall thickness of the outer tube and shall cut
through the entire length of the back section. Cuts shall be made completely through the tube forward
of the back section/lock ring area. Shearing, crushing, deep water dumping, or smelting may be utilized
when such methods of DEMIL are deemed cost effective or practicable and when authorized by the
appropriate authority or the DoD DEMIL Program Manager (DDPM).
Be sure the locking ring is not submerged in the CLR cleaner to avoid discoloration
of the ionbond coating on the lock ring.
12. SUPPRESSOR ALIGNMENT
When attaching a SureFire suppressor to a firearm for the first time, alignment should be
verified using a suppressor alignment bore rod prior to firing a suppressed shot. If alignment
is questionable please contact SureFire Technical Support at 714-545-9444.
