Sentry 9 Clamp On Adjustable Gas Block

So far so good

This gas block went on a large frame gas gun in 308 that has a .936 diameter barrel from Craddock Precision. Initially I had an adjustable gas block from another prominent company that ended up failing and breaking - so I figured why not go with one of the best. I aligned the gas block using a borescope to make sure that the port is perfectly aligned. I went to the range with the gas completely shut off and increased until I had bolt hold open on last round. So far, this gb has performed flawlessly. We shall see how it holds up after several matches.

Sentry 9 clamp on gas block

best gas block out there! Extremely tactile adjustments, that far exceed Superlative Arms! Would definitely recommend to anyone looking for an adjustable gas block!

Excellent precision craftsmanship. I'm normally not one to lend a review, but I felt like this warranted one. The gas block fits snugly on the barrel and is extremely light. Fit and functions flawlessly and looks like it belongs on a precision rifle. Thank your team for the quality craftsmanship.

The workmanship is very nice, the gas block works great the only bad thing is the shipping cost
