Art's Review of SLR Sentry 7 .750 Adjustable Gas Block w/ .450 in. Set Screw Spacing

I have a couple of these that I use with Larue barrels. The .450” spacing is dead on and you can tune the gas very precisely to your application/setup.
Pros:
  • Perfect fit on Larue barrel dimples.
Cons:
  • None
Best Used for:
  • Larue barrels
Would Recommend: Yes
