Midwest Industries
The Midwest Industries AR-15 Gas Block in low-profile .625" steel is engineered for shooters who want a clean, minimal aesthetic on their rifle without sacrificing function. This one-piece design sits low on the barrel, allowing it to tuck seamlessly under free-float handguards and rail systems—perfect if you're building a modernized AR or upgrading from a clunky, exposed block. Steel construction delivers the durability you need for sustained shooting, whether you're on the range, hunting, or training hard.
The three steel setscrews lock the block solidly to your barrel, keeping it indexed where you set it. A rock-solid gas block is non-negotiable; any movement affects reliability and shooter confidence. The .625" O.D. size fits barrels in that diameter range, so verify your barrel spec before ordering. Midwest Industries has built a reputation for no-frills, dependable AR parts that work—no marketing fluff, just engineering that holds up.
Whether you're assembling an entry-level rifle or assembling a higher-end build, a low-profile block gives you the option to run a modern handguard and rail system without the aesthetics—and functional penalties—of older designs. It's a straightforward upgrade that pays dividends in ergonomics and modularity down the line.
