The Seekins Precision Low Profile Adjustable Gas Block (0011510031) is a precision-machined, field-adjustable gas block built for AR-platform rifles, designed for builders, reloaders, and serious shooters who want precise control over their gas system for suppressed shooting, load development, or general reliability tuning. Machined from 1144 steel with a durable black Melonite finish and a compact low-profile footprint, the Seekins Precision (0011510031) fits cleanly under most free-float handguards without adding bulk or height to the build.

Special Features
- The side-facing adjustment screw allows the shooter to increase or decrease gas flow with a simple tool, and on many free-float handguard designs the adjustment can be made directly through the rail without removing any components from the rifle
- The brass-tipped front-facing locking set screw holds the adjustment position firmly in place once the desired setting is dialed in, preventing the gas screw from walking under the vibration of repeated firing
- The black Melonite finish is a salt bath nitride treatment applied to the steel, providing a hard, corrosion-resistant surface that resists carbon adhesion more effectively than standard Parkerized finishes, making cleaning faster and easier after heavy use
- The 1144 steel construction sets this block apart from lower-cost aluminum alternatives, providing the durability and heat resistance required for sustained fire, suppressed shooting, and the elevated gas pressures that come with certain loads
- The low-profile design at 1.37 inches tall and .94 inches wide is engineered specifically to clear the inside diameter of most modern free-float handguards, giving builders the benefits of an adjustable gas system without sacrificing handguard selection
- The side-access adjustment design is a deliberate engineering choice that keeps the block compact while still making tuning practical in the field or at the bench
Practical Benefits
- Properly tuning gas flow with the Seekins Precision Low Profile Adjustable Gas Block (0011510031) allows the shooter to optimize the rifle for a specific load, reducing wear on the bolt carrier group and extending the service life of other components in the gas system
- For suppressed shooting, an adjustable gas block is essentially a required upgrade, as suppressors dramatically increase back pressure and require the gas system to be dialed back to prevent over-gassing, excessive bolt speed, and reliability issues
- The side-access adjustment screw makes this block a practical choice for rifles with continuous-rail free-float handguards where the barrel is otherwise inaccessible without disassembly
- Builders running lightweight bolt carrier groups, reduced-power buffer springs, or low-mass buffer systems will find the adjustability of this block critical to getting the rifle to cycle reliably across a range of loads
- The Melonite finish and steel construction mean this block performs reliably under the heat generated by volume shooting at the range, competition, or in training environments where other components begin to show wear
- At 1.75 ounces, the block adds virtually no meaningful weight to the build, making it a practical upgrade for lightweight rifle projects where every ounce counts
- The set screw mounting style is straightforward to install with standard gunsmithing tools, and the compact dimensions give builders flexibility in barrel profile selection without compatibility concerns
The Seekins Precision Low Profile Adjustable Gas Block (0011510031) is a proven platform and a smart addition to any AR-15 build or upgrade project where suppressed shooting, precision load tuning, or long-term reliability under hard use is the goal.
