The LBE Unlimited ARGT308 Gas Tube delivers reliable gas system operation for AR-10 platform rifles chambered in .308 Winchester and 7.62x51 NATO. This mid-length configuration provides optimal cycling pressure while reducing bolt carrier velocity compared to carbine-length systems. Constructed from 304 stainless steel, this gas tube resists corrosion and maintains dimensional stability under high-temperature cycling.
What Makes This Different
The 304 stainless steel construction sets this gas tube apart from standard carbon steel alternatives that suffer from corrosion and heat-related warping. Mid-length gas systems reduce bolt carrier group stress by extending the dwell time, resulting in smoother cycling and improved brass life. The precise bore diameter ensures consistent gas flow without the restrictions common in budget alternatives. LBE Unlimited machines each tube to exact specifications, eliminating the gas flow inconsistencies that plague mass-produced components.
Key Features
- 304 stainless steel construction resists corrosion and heat distortion
- Mid-length configuration optimizes gas pressure for .308/7.62x51 cartridges
- Precision-machined bore maintains consistent .125-inch internal diameter
- Compatible with standard AR-10 gas blocks and upper receivers
- Heat-treated to withstand sustained rapid-fire sequences
- Rolled pin installation matches military specifications
- Nitride-finished exterior provides additional corrosion protection
Field testing demonstrates consistent cycling across temperature ranges from -20°F to 140°F without gas flow degradation. The mid-length system reduces felt recoil compared to carbine-length configurations while maintaining reliable function with both match-grade ammunition and military surplus rounds. Competition shooters report improved brass condition and extended barrel life when upgrading from carbine-length systems. The stainless construction maintains accuracy potential during extended shooting sessions where carbon steel tubes experience thermal expansion.
