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.
