M4SD, 5.56 entry level (QD mount)
The M4SD mounting system does not suffer from the wear prone issues of ratcheting systems common to the marketplace.
Our SDQD mounting system was designed to provide trouble free use.
The M4SD Does not include a mount
Materials:High Strength, High Temp, Corrosion Resistant 17-4PH Stainless Steel
Attachment:Griffin M4SD Mounts and USGI A2 spec compensators*
*Silencer interface was designed to fit the USGI A2 government contract compliant muzzle devices. We cannot guarantee fitment with an A2 style compensator due to the broad tolerance range of both import and domestic devices from various brands. For guaranteed fitment, we recommend the purchase a Griffin mount.
