Overview
The Guntec Low Profile Gas Block features a .750 diameter and is constructed from durable stainless steel, ensuring reliable performance and longevity in your build. Its low profile design allows for greater compatibility with a variety of handguard setups, helping to maintain a streamlined appearance while optimizing gas flow. This gas block is often used in builds where space is a premium, such as lightweight or precision rifles.
Builders on GunPartPicker first added the GUNTEC LOW PROFILE GAS BLOCK .750 DIA STAINLESS ST... to a build in April 2026.
Availability is good: it was in stock at one retailer or another nearly every day in August 2026, and today both retailers we track have it in stock. It dipped to $17.30 at BattleHawk Armory for a stretch in August 2026, well under its usual $31.99, so sales do come around. Buying today, the lowest price is $17.80 at BattleHawk Armory.
