Ballistic Advantage Mid-Length Gas Tube Features The Ballistic Advantage Mid-Length Gas Tube is machined to the correct 11.75 mid-length dimension so it drops into a mid-length AR-15 gas system without modification. Its Melonite finish increases resistance to the high heat and carbon fouling a gas tube is exposed to every time the rifle cycles which helps the tube hold up over a long service life compared to an untreated tube. The Black finish matches standard AR-15 furniture and metal components keeping the build looking uniform front to back. Ballistic Advantage builds the tube to reliably deliver gas pressure from the gas block to the bolt carrier group which is essential to consistent cycling and reliable function. A roll pin is included with the gas tube giving builders everything needed to secure it to the gas block during assembly without sourcing a separate part. This makes the tube a simple complete-in-the-box solution for a new build or for replacing a worn or damaged gas tube on an existing mid-length AR-15. Ballistic Advantage is a recognized AR-15 parts manufacturer known for precision-made components and this gas tube reflects that same attention to fit and finish. For any shooter building repairing or upgrading a mid-length AR-15 gas system this Melonite-finished gas tube is a dependable no-fuss replacement part.
