Armaspec A2 Spacer for SRS/SMB – AR-15 Buffer System Compatibility

The Armaspec A2 Spacer enables proper installation of Armaspec's Stealth Recoil Spring (SRS) and Sound Mitigation Buffer (SMB) systems in AR-15 rifles equipped with A2-length receiver extensions. This precision-machined spacer closes the dimensional gap between standard buffer systems and A2 buffer tubes, ensuring correct spring compression and reliable cycling.

Constructed from durable polymer, the spacer installs between the buffer system and the buffer tube end plate. Direct compatibility with Armaspec SRS and SMB products only—verify your buffer tube length before ordering. Installation requires disassembly of the buffer system and basic armorer's tools.
