Spike's St-t2 Tungsten Heavy Buffer

The Spike's ST-T2 Tungsten Heavy Buffer is a purpose-built heavy buffer system engineered to reduce felt recoil impulse and cycle time in AR-platform carbines. Constructed with a crushed tungsten mil-spec bumper and solid aluminum bullet, this 4-ounce buffer delivers measurably softer shooting characteristics compared to standard carbine buffers, making it a proven choice for shooters seeking smoother operation and reduced muzzle rise during rapid-fire sequences.

The tungsten-loaded design provides superior shock absorption properties, translating to noticeably quieter cycling and reduced wear on critical receiver components. At 4 ounces, the ST-T2 significantly exceeds standard mil-spec buffer weight (3 ounces), which directly impacts bolt carrier velocity and dwell time. The black anodized aluminum construction offers corrosion resistance and a professional appearance, while the maintenance-free design eliminates the need for periodic cleaning or lubrication of internal components—a critical advantage for field-deployed systems or high-round-count training environments.

This buffer is optimized for operators, competitive shooters, and patrol units running standard mil-spec receiver extensions (buffer tubes). The heavier tungsten-composite weight is particularly effective with suppressed systems or during precision-focused applications where controlling recoil signature improves follow-up shot accuracy. It performs as a drop-in replacement for factory carbine buffers, requiring no additional tools or modifications to install.

Spike's Tactical has established market recognition for proprietary buffer designs that balance performance and affordability. The ST-T2 competes in the heavy-buffer category alongside similar premium offerings, differentiated by its tungsten composition and verifiable improvements in recoil management and shooter comfort during extended shooting sessions.
