LBE Unlimited ARGTC Gas Tube Carbine Length 304 Stainless Steel AR-15 - Roll Pin Included
Product Description
Whether you are building a new upper from scratch or replacing a worn-out component, a reliable gas tube is critical to keeping your AR-15 running smoothly. Low-quality gas tubes can warp under intense heat, erode at the port opening, or leak gas over time, which leads to short-cycling and frustrating malfunctions. The LBE Unlimited Carbine Length Gas Tube (ARGTC) provides a tough, dependable solution built to handle high volume strings of fire and keep your rifle cycling reliably.
This gas tube is made in the USA from premium 304 seamless stainless steel tubing. Because it is completely seamless, it handles high-pressure gas bursts without the structural weak points or splitting risks common to cheaper welded tubes. Stainless steel is also highly resistant to the corrosive byproducts of burnt gunpowder and harsh outdoor elements, ensuring your gas block assembly functions cleanly without choking out your rifle over time.
Designed as a direct drop-in replacement for any standard carbine-length gas system, it features clean, precise factory bends that slide perfectly into your upper receiver and align seamlessly with your bolt carrier's gas key. The package also includes a fresh gas tube roll pin, saving you a trip to the store and giving you everything you need for a quick, trouble-free installation on your workbench.
Each individual factory retail package includes one genuine LBE Unlimited Carbine Length Stainless Steel Gas Tube and one matching gas tube roll pin.
*Armorer Bench Notes & Installation Guidance: The LBE Unlimited ARGTC (Part # ARGTC) is dimensioned specifically for standard **AR-15 carbine-length gas systems** (typically found on 10.5-inch to 16-inch barrels with a gas port roughly 7 inches from the receiver face). It will not fit pistol, mid-length, or rifle-length barrels. When assembling your upper, make sure the gas block is perfectly centered over the barrel's gas port before securing it. Ensure the open gas port hole on the tube faces downward into the gas block cavity, and use a dedicated roll pin punch to install the included pin without marring the stainless finish. Always verify alignment by manually sliding your bolt carrier group forward to ensure the gas key accepts the gas tube smoothly without binding or catching.
