The Sound Mitigation Buffer SMB is a single-stage drop-in replacement for your standard buffer and spring. The Sound Mitigation Buffer is designed to keep the buffer spring from rubbing against the inner wall of the buffer tube providing smooth,quiet operation. Pat. Pending
SMB-Carbine, SMB-H, SMB-H2, SMB-9, SMB-H3, SMB-308
|SMB-Carbine||Equivalent to a standard 3oz carbine buffer|
|SMB-H||Equivalent to an H 3.8oz buffer|
|SMB-H2||Equivalent to an H2 4.6oz buffer|
|SMB-H3||Equivalent to an H3 5.4oz buffer|
|SMB-308||Equivalent to a 5.7oz 308 buffer and the correct length to allow for proper over travel when used with large platform (.308, 6.5 Creedmoor, etc.)|
|SMB-9||Equivalent to a 9mm / PCC buffer which is typically around 6.2oz and is also extended to prevent excessive over travel when using PCC bolt carrier groups|
- 1. Insert polymer base with guide rod into the buffer tube.
- 2. Insert desired spring on the guide rod.
- 3. Insert the buffer over the spring.
Note: Spring will fully set after approximately 100 shots. Main spring can be trimmed at .25 lbs per coil to reduce tension up to a max of 12 coils.
