Bought a rail but need some of that clicky goodness in your life? Check this out then!

Weighing in at 1.6oz, this Arkto .625 gas block is a click adjustable gas block that can meter your gaseous needs with the tactile feel and adjustment retention that you crave. The adjustment screw is NiPTFE coated to reduce fouling and increase lubricity and has six (6) grooves that interface with a tried-and-true detent ball mechanism to give 24 clicks worth of adjustment across the port.

To aid in gauging relative port position, there is a small  mark on the adjustment screw to indicate the fully-open port position.

To aid in a perfect installation, the gas port is milled all the way through the top of the block. Just center on your gas port, tighten the clamping screws and you are in business!

A complete set of allen wrenches and a 2mL vial of Vibratite are included with purchase.
