The Aim Sports Mid-Length AR-15 Gas Tube (brand part number XDB15MGAST) is a precision-manufactured stainless steel gas tube sized for mid-length gas systems, a popular setup on 16-inch-barrel AR-15 carbines that softens recoil impulse compared to a carbine-length system. It routes propellant gas from the gas block back to the bolt carrier group to cycle the action, so a correctly sized, corrosion-resistant tube is essential for reliable function. Aim Sports machines this tube from stainless steel to hold up to repeated heat cycling without flaking or corroding. It’s a straightforward, affordable way to replace a damaged gas tube or finish out a mid-length gas system build.
