Lantac
Overview
The Lantac Rifle Length Gas Tube is designed for use in rifle-length gas systems, providing optimal gas flow and reliability for your build. Made from carbon steel and finished with a nitride treatment, it offers enhanced durability and corrosion resistance, ensuring consistent performance under various conditions. This gas tube is commonly found in builds featuring a rifle gas system with a 5.56 NATO caliber, making it a solid choice for those looking to optimize their AR-15 platform.
LANTAC Rifle Length Gas Tube - Nitride was the ninth most added gas tube on GunPartPicker in August 2026, behind the Strike Industries AR-15 Gas Tube - Carbine Length, with about 3% of all gas tubes added to builds. Up from #11 in July. Builds with this gas tube are mostly chambered in 5.56 NATO (67%, then .308 Win 17%), nearly all on rifle-length gas, and mostly AR-15 (83%, then AR-10 17%).
Availability is good: it was in stock at one retailer or another nearly every day in August 2026, and today 5 of the 6 retailers we track have it in stock. Prices barely moved in August 2026, holding around $21.99, so there haven't been real sales lately. Buying today, the lowest price is $22.05 at GritR Sports, which matches the best price we saw in August.

Lantacs rifle length gas tube in nitride works on my 20 inch build. Pin alignment was correct. The nitride coating is darker than parkerized and resists corrosion better. Cycles consistently with M193 or M855 ball ammo.
