Armaspec ARM653-ML Mid-Length Gas Tube AR-15/AR-10 Stainless Steel 11.75"

The Armaspec ARM653-ML is a drop-in mid-length gas tube built for AR-15 and AR-10 platforms. Machined from stainless steel for corrosion resistance and long service life, this tube measures 11.75" end-to-end and is sized to pair with a mid-length gas system on standard AR-pattern uppers.

Designed as a direct replacement component, the ARM653-ML installs between the barrel's gas port and the gas block, then runs back through the upper receiver to deliver propellant gas to the bolt carrier key. The stainless steel construction provides consistent gas flow and stands up to the heat and pressure of repeated firing cycles, while the silver finish blends cleanly with stainless or phosphate uppers.

This gas tube is made in the USA by Armaspec and is intended for builders and gunsmiths assembling, servicing, or upgrading a mid-length AR-15 or AR-10. It is sold as a single gas tube only.
