Description
The LANTAC USA M-SPEC Intermediate Gas Tube is a precision-manufactured replacement AR-15 gas tube cut for rifles running an intermediate-length gas system. At a true 13.66″ overall length, it drops into a standard AR-15 upper receiver with no fitting required.
Each tube is precision manufactured from 306 stainless steel extruded tubing for excellent corrosion resistance and a long service life under hard use. The natural stainless steel finish is both functional and clean-looking, and the tube is laser engraved for positive identification. A matching gas tube roll pin is included for installation right out of the package.
Whether you are replacing a worn or damaged gas tube, building a new intermediate-length AR-15, or completing a custom upper, the M-SPEC Intermediate Gas Tube delivers the consistent fit and finish LANTAC USA is known for.
