Tacfire AR-10 Heavy Buffer 4.9 oz

The Tacfire AR-10 Heavy Buffer 4.9 oz is a precision bolt carrier component designed for shooters and tactical professionals who require reliability in intermediate to long-range platforms. This heavy buffer is specifically engineered for the AR-10 platform, where reliable cycling and reduced recoil impulse are essential for accuracy and shooter control. Whether you're setting up a precision rifle, conducting duty carbine work, or optimizing a competition build, this buffer plays a crucial role in managing energy and cycling ammunition.

At a weight of 4.9 oz, the Tacfire AR-10 Heavy Buffer adds mass to the bolt carrier assembly, which slows the rearward movement of the carrier and reduces peak pressure spikes during cycling. This weight specification is ideal for tuning rifle dynamics when using heavier ammunition loads, adjusting dwell time, or minimizing wear on critical components. The increased mass also helps to reduce felt recoil and muzzle rise, allowing for faster follow-up shots and improved target reacquisition.

AR-10 owners will find the most benefit from this heavy buffer when using suppressed setups, magnum rifle calibers, or precision match ammunition that requires controlled cycling. Installation is straightforward—simply remove your existing buffer from the receiver extension and install the Tacfire unit, which integrates seamlessly with standard AR-10 receiver extensions and buffer tubes without any modifications.
