Spike's Tactical ST-T3 Heavy Buffer for AR-15

Spike's Tactical ST-T3 Heavy Buffer

The ST-T3 represents a purposeful evolution in buffer technology, designed for shooters who demand more from their AR-platform rifles. This heavy buffer addresses the real-world challenges faced by those running suppressed weapons, heavily modified rifles, or systems prone to overgassing.

Design and Construction

The ST-T3 employs a straightforward but effective approach: three solid tungsten weights machined from bar stock, capped with a Mil-Spec bumper. This configuration delivers measurable improvements without the maintenance burden of fluid-filled alternatives. There are no seals to fail, no leaks to manage—just reliable performance that requires nothing from you but shooting.

Performance Benefits

Recoil Management: The heavier mass significantly reduces felt recoil and muzzle rise, particularly valuable when firing rapid strings or running the rifle in full-auto configurations.

Reliability: By moderating the bolt's rearward velocity, the ST-T3 eliminates bolt bounce and ensures consistent cycling across varying ammunition types and suppressor configurations.

Versatility: While optimized for .223/5.56, the buffer functions reliably across all AR-platform calibers.
