Luth Ar Standard Gas Tube

The Luth-AR Standard Gas Tube is a stainless steel rifle-length gas tube engineered for AR-15 platform builds requiring reliable gas system operation. This component delivers the gas impulse from the barrel to the bolt carrier group, making it fundamental to semi-automatic cycling. Luth-AR's stainless steel construction resists corrosion and maintains dimensional stability across extended shooting sessions, critical for maintainers building or servicing mil-spec and civilian AR-15 configurations.

Rifle-length gas tubes are optimized for full-length receiver extensions and are commonly paired with 16-inch to 20-inch barrel builds. The stainless steel material withstands high-temperature cycling and minimizes galling during assembly and disassembly, reducing maintenance friction. At 6 inches in length and weighing just 0.13 lbs, the Luth-AR tube integrates seamlessly into upper assemblies without adding significant weight or affecting balance. Proper gas tube selection ensures consistent bolt carrier speed, reduces short-stroking risk, and supports reliable function across standard 5.56 NATO and .223 Remington loads.

This gas tube is suited for shooters assembling or maintaining AR-15 rifles for duty, training, or civilian competition. Technicians rebuilding mil-spec uppers, gunsmiths servicing patrol rifles, and dedicated competitors replacing worn gas system components will find this component meets standard AR-15 specifications. Whether replacing a damaged tube or building a custom rifle from component parts, the Luth-AR Standard Gas Tube provides a proven stainless steel solution that supports the long-term reliability of the AR platform.
