These mil-spec (1.148″) diameter carbine buffer tubes are machined from solid 7075-T6 aluminum bar stock and are 1.5″ longer than your standard tube. These allow for 5-positions to be selected.
Perfect for you larger guys or if you just don’t care for the carry handle smacking you in the nose when you crawl up on your big bore AR.
These tubes have the same internal dimensions as a standard tube, so standard carbine length springs and buffers should be used.
Overall length of the tube is 9.3″
Weight is 7.5 ounces.
Available in black anodized finish, or in-the-white (bare aluminum, no finish)
