TacFire AR-15 Heavy Buffer Features The TacFire AR-15 Heavy Buffer is built as a solid weight design specifically for 9mm pistol caliber carbines which require a longer dwell time than standard 5.56 rifles to cycle the action reliably. This solid construction eliminates the rattling and clicking noises that come from buffers containing internal moving weights resulting in a quieter smoother cycling action. At 5.5 ounces the added mass slows bolt carrier velocity just enough to improve function and reduce the harsh recoil impulse common to PCC-pattern AR builds. Made from steel and finished in black nitride the buffer resists the wear and corrosion that come with sustained use. Manufactured in the USA this buffer is backed by TacFire s limited lifetime warranty giving shooters confidence in its long term durability. Installing a properly weighted buffer is one of the simplest and most effective ways to tune reliability in a 9mm AR-15 build correcting cycling issues that stock components sometimes struggle with. PCC shooters running suppressors or shorter gas systems in particular benefit from the added dwell time this heavier buffer provides. Shooters looking to smooth out the function of their 9mm AR-15 carbine will find this TacFire Heavy Buffer a simple effective upgrade.
