Precision Machined Steel Construction
Crafted from high-strength steel, the TacFire Clamp-On Gas Block is built for maximum durability and long service life. Its robust construction withstands extreme heat, pressure, and recoil forces, ensuring it won’t shift, warp, or fail even under sustained firing conditions.
The black Parkerized finish enhances corrosion resistance and wear protection while providing a tactical matte appearance that complements any rifle build. This rugged coating reduces glare, resists rust, and maintains a clean, professional look over time — even in harsh field conditions.
Clamp-On Design for Secure, Damage-Free Installation
Unlike set-screw or pinned styles, the clamp-on design offers an easy, secure, and non-invasive installation method. Dual clamping screws provide even pressure around the barrel, ensuring a tight, slip-free fit without marring or damaging the barrel’s surface.
This makes the TacFire MAR001CO ideal for builders who want a strong hold with simple installation and easy adjustability. Once tightened, it stays firmly in place, maintaining consistent gas flow and cycling even after extended use.
Low-Profile for Modern Handguards
The low-profile design of the TacFire gas block allows for seamless compatibility with most free-float and slim handguards, giving you more rail space and customization options for optics, lights, and grips.
Its compact size eliminates interference issues and creates a clean, professional rifle silhouette. Whether you’re building a precision AR-15, M4 carbine, or modern sporting rifle, this gas block fits discreetly under the handguard while maintaining full functionality.
Reliable Performance for .750" Barrel Profiles
Designed for barrels with a .750-inch diameter at the gas journal, the TacFire MAR001CO is one of the most common and versatile fits in the AR market. This makes it ideal for a wide range of calibers and configurations, including 5.56 NATO, .223 Remington, .300 Blackout, and similar gas-operated systems.
When installed correctly, it ensures smooth cycling, consistent gas pressure, and dependable performance, whether you’re at the range, in competition, or in the field.
