TacFire Buffer Features The TacFire Buffer is machined from aluminum and finished with a durable black anodized coating that resists wear from repeated cycling inside the buffer tube. At a mil-spec 3 ounce weight it provides the correct mass needed for reliable bolt carrier group cycling across a range of ammunition types. This makes it a smart choice both for restoring an AR-15 to factory-correct function and for builders assembling a rifle from individual parts. Measuring 3.37 inches in length it fits standard AR-15 buffer tubes without modification. Proper buffer weight is essential to smooth reliable AR-15 operation and this TacFire buffer takes the guesswork out of matching that spec. Its anodized finish stands up to the friction and heat generated during firing without degrading over time. Installation is simple requiring only removal of the old buffer and insertion of the new one into the buffer tube. This is a straightforward dependable upgrade or replacement part for keeping an AR-15 running the way it was designed to.
