Arrived fast and was exactly what was expected

Good gas block for criterion core. No complaints, easy install. Rooftop is my new go-to. Customer service, shipping are industry standard-bearers.
Joe (verified owner) –
Good quality. Removes the gap between shoulder and gas block. A little looser than expected on criterion core barrel (spins freely on journal). Would buy again.
Eric R. –
This is the perfect gas block to mate with a Criterion Core barrel. Machined from 4140 steel, allows the gas block to expand at the same rate/heat as the barrel creating a tight seal during hard use that insures consistent gassing.
