Excellent gas block


Okay first off fit and finish are nice. Secondly and probably the most important feature of this gas block is the fact you can drop a small rod through the top and alight the gas port and block in 1 go and torque the set screws and done. No secondary adjusting or hoping you got it “perfect”. It’s a a simple but great idea.
