The Battle Arms Development Workhorse Low Profile Gas Block (.750) is a solid choice for builders looking for a rugged, "no-frills" component that fits under slim handguards. It’s designed specifically to balance weight and durability without the extra bulk of adjustable models.
Key Specifications
- Journal Size: 0.750 inches (Standard for most AR-15 barrels).
- Material: 4140 Chromoly Steel.
- Finish: Nitride (Black).
- Attachment: Two set screws (bottom-style).
- Weight: Approximately 1.3 oz (very lightweight).
Highlights for Your Build
- Low Profile Geometry: The "Workhorse" series is specifically tapered to provide maximum clearance for modern, tight-fitting M-LOK or KeyMod rails.
- Durability: Unlike aluminum blocks that can erode over time under high heat, the 4140 steel construction handles rapid-fire strings and suppressed use much more effectively.
- Nitride Coating: This finish provides excellent corrosion resistance and makes cleaning carbon buildup significantly easier.
