Brownells Ar-15 Modular Gas Block, 0.750''$37.49
Availability: In Stock

The Brownells AR-15 modular gas block kit with rail brings serious configuration flexibility to your rifle build. Unlike fixed gas blocks that lock you into one mounting setup, this 0.750" model comes with an integral Picatinny rail and the ability to add up to three additional rails in the positions that matter for your mission. Whether you're mounting a laser, tactical light, night vision optic, or backup sight, you can attach and remove side and bottom rails with just two screws per rail—no permanent commitments, no guesswork.
Built from 6061 billet aluminum, the gas block delivers the strength you need for demanding use without unnecessary weight. The precision-machined construction pairs with three hardened steel setscrews that anchor the block securely to your barrel, so it stays put through training, hunting, or competition cycles. The modular design means you can reconfigure your setup between range sessions or tactical exercises without swapping the entire block.
This is purpose-built for shooters who want their AR platform to adapt to the job at hand—not the other way around. Brownells' approach here is practical: solid engineering, simple installation, and the freedom to add and remove accessories as your needs change.
