VLTOR A5 Complete Buffer Kit

The VLTOR A5 buffer system represents a fundamental reimagining of the AR-15 recoil system, combining a proprietary receiver extension tube that is 3/4 inch longer than standard carbine tubes with intermediate-length buffers and rifle-length action springs. This unique configuration creates what many consider the optimal buffer system for AR-15 rifles, delivering smoother cycling, reduced felt recoil, and expanded reliability across the entire operational envelope. The A5 system regulates carrier velocity and changes the recoil impulse in ways that standard carbine systems simply cannot match.

The complete kit includes the A5 receiver extension tube, an A5H2 buffer (5.3 oz), a rifle-length buffer spring, castle nut, and end plate. The longer tube allows the rifle-length spring to work with the intermediate buffer at full extension, resulting in a slower, more controlled bolt movement that keeps shooters on target through rapid strings. The system opens up tuning possibilities by offering five different buffer weights from A5-H0 (3.8 oz) to heavier options, allowing precise optimization for specific barrel lengths, gas systems, and suppressor configurations.

Real-world testing consistently shows the A5 system delivers superior performance compared to standard carbine setups. Shooters report noticeably smoother recoil impulses, better lock time for improved accuracy, and more forgiving reliability with varying ammunition and environmental conditions. The system has become the go-to recommendation from serious instructors and armorers for anyone building a duty rifle or premium AR-15. While more expensive than a standard buffer tube kit, the A5 system's performance benefits make it a legitimate upgrade that transforms how the rifle feels and functions.
