Builders have been adding the Luth-AR AR-15 Gas Tube Stainless Steel Pistol to their builds on GunPartPicker since March 2026. All time, it ranks #58 of the 107 gas tubes builders have added.
Availability is good: it was in stock at one retailer or another nearly every day in September 2026, but today only Brownells has it in stock. It dipped to $10.95 at BattleHawk Armory for a stretch in September 2026, under its usual $11.74, so sales do come around. Buying today, the lowest price is $11.74 at Brownells, above September's low of $10.95, so a better deal may come back.
