Clamp-on gas blocks are ideal when you don’t want to dimple your barrel, while set screw gas blocks are lighter and great for minimalist builds.
Suppressor-Friendly Compatibility
Yankee Hill gas blocks are excellent for suppressed rifles. Their precise gas control ensures reliable cycling and reduces excess blowback when paired with YHM suppressors like the Turbo K or Resonator.
