Seekins Precision Select Adjustable Gas Block for AR-15/LR-308 - Steel Black$114.00
Availability: In Stock
A Seekins Precision Select adjustable gas block gives you hands-on control over your AR's reliability and handling. This .875" steel gas block mounts to your barrel and lets you dial in gas flow to match your ammunition, suppressor setup, and shooting conditions—so you get consistent cycling without excessive bolt carrier speed or gas tube strain. Built in steel with a durable Melonite finish, it's made to last through thousands of rounds and hard use in the field or at the range.
Adjustable gas blocks are essential for shooters running suppressors, shooting subsonic loads, or tuning a precision rifle for accuracy and reliability. By restricting gas flow to just what your gun needs, you reduce recoil, lower wear on components, and improve shot-to-shot consistency. The Seekins design is known for holding zero and surviving real-world duty and hunting conditions without gumming up or creeping loose.
Melonite is a proven case-hardening finish that resists corrosion and wear better than standard parkerizing. It's black, professional-looking, and earned its reputation on military and law enforcement rifles where durability matters. Whether you're building a suppressed 5.56 for hunting, a .308 precision rifle, or optimizing an existing AR platform, this gas block gives you the tuning flexibility that factory or fixed designs simply can't match.
This block is sized for .875" diameter barrels. Measure or verify your barrel's gas block journal before ordering—using the wrong size will result in a poor fit and potential reliability issues.
An adjustable gas block lets you dial gas flow to match your specific setup: ammunition type, suppressor, or desired recoil impulse. This improves reliability with marginal loads, reduces noise and recoil signature, and can extend component life by preventing over-gassing.
Installation requires removing your handguard and barrel and fitting the block to the gas port. If you're not comfortable with rifle assembly, have a gunsmith handle it. We provide the block only—check the product contents for what's included in the box.
Yes. Suppressors increase back-pressure and gas flow; an adjustable block lets you dial it back to safe, reliable levels without over-gassing the bolt carrier.
