Low-Profile Gas Block 0.75" – Schmeisser®

The Schmeisser^® Low-Profile Gas Block (0.75") is a compact and highly durable gas adapter designed for AR-15 platforms. Compatible with most narrow (SLIM) handguards, it delivers exceptional performance for rifles with 0.75" outer diameter barrels.

Engineered for Durability

Precision-crafted from high-grade 42CrMo4 stainless steel sourced from Germany, this gas block is built to withstand extreme conditions—especially the corrosive effects of combustion gases. Its robust construction ensures long-term reliability and superior performance.

20-Position Click Adjustment with Auto-Locking

The Schmeisser gas block features 20 clearly defined adjustment positions, each secured with an audible, tactile click. The automatic locking mechanism ensures settings stay in place during operation, and the position can be recalled easily without visual confirmation—perfect for suppressed shooting setups.

Enhanced Gas Seal and Cleaner Operation

With tight tolerances and precision machining, the block delivers an exceptionally sealed interface to minimize gas leakage. Its symmetrical design supports free-floating barrel systems, and the strategically placed locking pin reduces carbon buildup by distancing it from the gas channel.

Complete Installation Package

The gas block ships ready for installation, including a locking pin, set screws, and an adjustment key. Its streamlined profile makes it ideal for low-clearance setups without compromising functionality or durability.

Each unit undergoes rigorous quality control under Schmeisser’s internal Quality Check program. Meeting stringent military specifications, this gas block is engineered to perform flawlessly in both professional and civilian applications.
