Feed Your AR-15 the Gas It Needs

The SLR Rifleworks Sentry Adjustable Clamp On Gas Block gives AR owners total control over their rifle's gas systems, giving them the chance to fine-tune the gun with different ammo or with an attached suppressor.

The SLR Rifleworks Sentry Adjustable Clamp On Gas Block doesn't operate with any small screws or balls like other gas blocks, removing the chance these parts could fail or get lost.

  • Comes in .625, .750, .875 and .936 diameters
  • Constructed from 4140 billet steel
  • Features QPQ Melonite finish

The SLR Rifleworks Sentry Adjustable Clamp On Gas Block is adjustable with an included tool and features a clamp-on attachment design that is guaranteed to provide a solid gas seal.
