Barrel Extenders to increase your barrel length as long as you need. Comes in 3 and 4 inches sections. (See actual dimensions below)

Modern M4 barrel diameter.

These are very high quality extenders with tight tolerances.

Can be permanently pinned, welded, or just screwed on tightly. Finish options are black or shiny unfinished steel.

Standard 5.56/.223 1/2 x 28 male/female threads on both ends.



- Overall length of 3.5 or 4.5 inch

- Diameter: .70

- Threads: 1/2 x 28

- Steel construction

- Available in Black or unfinished (shiny)


* Note: Actual Extender length is different from overall length added to barrel. This is due to the overlapping threads, which means the actual length added to barrel will be a little more than 1/2 inch less than actual size.
