Extended Carbine Buffers

AR-15 Extended Carbine Buffer – Optimized Length for Special Receiver Extensions

The AR-15 Extended Carbine Buffer is designed for use in AR-15/M4 platforms with A5 length receiver extensions or other specialized buffer tube setups that require a longer buffer body. By increasing the overall buffer length while maintaining precise weight tuning, extended carbine buffers help prevent bolt carrier overtravel, improve cycling smoothness, and reduce wear on internal components.

Available in various weight configurations (Standard, H2, H3, and H4), extended carbine buffers give shooters the flexibility to fine-tune their rifle’s performance for suppressed builds, SBRs, and custom gas systems.
