Solid gas block, Easy installation!
Love using this gas block! It's super low profile and fits under my STNGR HWK and VLCN handguards. The included allen wrench is long enough to adjust the gas settings with the handguard still attached (although this will vary with the handguard and gas system lengths). Installation was super easy on my Rosco Bloodline barrels, as all that was required was lining up the set screw with the barrel's dimple (pre-dimpled from the manufacturer). I did not use Locktite as the gas block heats up too much for it to hold reliably, and the screws are still tight after firing a couple hundred rounds. Looks very easy to take apart to service or clean if needed. The locking positions in the gas block are distinct enough to use repeatably, but a little mushier than I had hoped. All things considered, still a great product at a competitive price.
