Lantac
Overview
The Lantac Intermediate Length Gas Tube is designed for use in gas systems that require an intermediate length, making it an essential component for optimizing gas flow and cycling in your AR-15. Crafted from carbon steel and finished with a nitride treatment, this gas tube provides durability and corrosion resistance, ensuring reliable performance during operation. This gas tube is commonly found in builds featuring an extended rifle gas system, particularly those chambered in 5.56 NATO.
LANTAC Intermediate Length Gas Tube - Nitride ranked #43 of the 63 gas tubes builders added on GunPartPicker in August 2026. Builders have been adding it to their builds on GunPartPicker since March 2026. All time, it ranks #48 of the 95 gas tubes builders have added.
Availability is good: it was in stock at one retailer or another nearly every day in August 2026, and today 5 of the 7 retailers we track have it in stock. Prices barely moved in August 2026, holding around $22.05, so there haven't been real sales lately. Buying today, the lowest price is $21.99 at Optics Planet, which matches the best price we saw in August.
