Faxon Firearms Pistol Length Gas Tube - Stainless Steel AR-15

The Faxon Firearms Pistol Length Gas Tube delivers consistent cycling performance for AR-15 builds requiring precise gas system operation. This stainless steel component ensures reliable function in compact rifle configurations where standard gas tubes fall short. Built to withstand high-pressure gas flow and extreme temperatures, it maintains dimensional stability through thousands of rounds.

What Makes This Different

Unlike standard carbon steel gas tubes that can corrode and restrict gas flow over time, this stainless steel construction resists fouling buildup and maintains consistent inner diameter. The pistol length specification provides optimal gas timing for barrels 10 inches and shorter. Manufacturing tolerances held to +/- 0.001 inches ensure proper alignment with gas blocks and bolt carriers across multiple cycling conditions.

Key Features

• 316 stainless steel construction resists corrosion and fouling accumulation
• Pistol length gas system - 4.0 inches from gas port to gas block
• 0.125-inch inner diameter maintains consistent gas pressure
• Compatible with standard AR-15/M4 gas blocks and bolt carrier groups
• Precision machined ends for secure gas block retention
• Heat treated for dimensional stability under rapid fire conditions
• Made in USA with lifetime manufacturer warranty

Field testing demonstrates reliable cycling with both 55-grain and 77-grain ammunition across temperature ranges from -20°F to 140°F. The stainless construction eliminates the gas restriction issues common with corroded carbon steel tubes after extended use. Competition shooters report consistent bolt timing through high round count training sessions without cleaning intervals affecting performance.
