Armaspec A5 Spacer for SRS/SMB Buffers

The Armaspec A5 Spacer (brand part no. ARM154-RFLA5) is a small buffer-tube spacer built to configure an Armaspec Stealth Recoil Spring (SRS) or Sound Mitigation Buffer (SMB) for use with A5-style AR-15 stocks. A5 buffer tubes are longer than a standard carbine tube, and Armaspec designed this spacer to take up that extra length so its SRS and SMB buffer systems index and function correctly inside it. Without the correct spacer, a buffer system sized for a standard carbine or rifle tube can bottom out or cycle incorrectly in an A5-length tube. This spacer is a simple, inexpensive way to make sure an SRS or SMB buffer set works exactly as designed on an A5-pattern stock.

Key Specifications

• Purpose-built as an A5 buffer tube spacer, sizing an SRS or SMB buffer system for correct fit in A5-length tubes.
• Classified as a buffer system component, meant to be paired with Armaspec’s SRS or SMB buffer kits rather than run alone.
