Spike's St-t1 Tungsten Heavy Buffer

The Spike's Tactical ST-T1 Tungsten Heavy Buffer is a purpose-built recoil management component designed for AR-platform carbines and rifles. This buffer is engineered to reduce bolt carrier velocity and impulse transmission, making it ideal for operators looking to enhance their shooting experience.

Weighing 0.19 lbs, the ST-T1 is significantly heavier than standard 1.1-ounce carbine buffers, which helps slow bolt carrier acceleration and reduces peak impact forces on the buffer tube and receiver extension. The buffer features a crushed tungsten composite bumper paired with a solid aluminum body, contributing to softer cycling and reduced noise signature during operation.

This buffer is particularly beneficial for those running suppressed or short-stroke configurations, where standard buffers may transmit excessive recoil impulse. It also performs well on non-suppressed carbines, enhancing accuracy during sustained fire by managing felt recoil. Regular inspection and maintenance are recommended to ensure optimal performance over time.
