The Seekins Precision Low Profile Adjustable Gas Block (brand part number 0011510031) lets AR-15 builders dial in exactly how much gas cycles the action, instead of living with whatever a fixed block sends back down the tube. Seekins Precision finishes the block in black Melonite for corrosion and wear resistance through extended strings of fire, and keeps the profile low at 1.37 inches tall by .94 inches wide so it tucks under most free-float hand guards without a fitment fight. Regulating gas flow this precisely opens the door to running low-mass bolt carriers, lighter buffers, and softer springs for noticeably reduced felt recoil, a real advantage for a suppressed build or a competition gun that needs to stay flat between shots.
