FN America is widely known for manufacturing some of the country's best AR-15 accessories and parts for build or replacement.  This Carbine Buffer Tube is a perfect example of FN America's dedication to providing consumers high-quality firearm parts at excellent prices.

  • Type: AR-15 Mil-Spec
  • Use: New Builds/Maintenance
  • Material: 6061 T6 Billet Aluminum

A carbine buffer tube - sometimes known as a receiver extension tube - has two primary purposes.  The first and most obvious is it allows attachment of a collapsible stock.  It also holds the buffer assembly and the buffer spring, which helps with recoil and allows the bolt carrier group's back and forth movement to eject spent cartridges and load a new shell in the chamber.

This buffer tube from FN America is made from Mil-Spec 6061 T6 billet aluminum for more significant heat and corrosion resistance.  Whether you're building, improving, or performing maintenance on an AR-15, an FN America Carbine Buffer Tube is the best choice you can make.
