An adjustable gas block can drastically improve your rifle's characteristics and longevity, but making those adjustments almost always requires fiddling with long keys or partially disassembling your rifle. Not exactly a field expedient procedure. The Seekins Precision Select Adjustable Gas Block was designed from the ground up to correct that and provide the end user with true tool-free on-the-fly gas system adjustments. Quickly switch from suppressed to unsuppressed whenever you want with just the flip of a switch! Rifle getting dirty and need more gas? No need to clean or disassemble your firearm, simply bump the gas selector over to keep your rifle up and running and minimize your down time.

  • 40-positions for fine initial adjustment
  • Tool-free gas selection switch
  • Perfect for suppressed and unsuppressed use
  • High strength tool-steel construction
  • Melonite finish for corrosion resistance
  • Fits .875" gas seats

For suppressor hosts, simply start with the suppressor installed and set your initial gas setting with the fine tuning adjustment on the front of the gas block. The ideal setting is one click higher than what will reliably lock the bolt open on an open mag. From there, simply install the gas switch in the left most position to set your minimum gas setting. From there, if the rifle gets dirty or you remove the suppressor you can simply push the switch over to the right to add gas to the system and keep your rifle running reliably.

Proof that the American Dream is alive and well, Seekins Precision began in 2004 with a single product. Their rapid growth has carried them from the early days of manufacturing scope rings to include more than ten major product lines, including complete rifles.
