Best gas block. no carbon locking, no long hex wrenches. - Riflespeed Gas Control .750in Assembly Block

To my knowledge, this is the only adjustable gas block design on the market that doesn’t require frequent cleaning to avoid carbon locking.

From a performance standpoint, the main con is a little added weight, but it’s barely noticeable.

Before you install this gas block, make sure to remove any burrs or sharp edges inside the gas port hole, since these can shave off slivers of the copper jacket which can get stuck in the pin.
