Need Adjustable Gas Block Suggestions for SBR build

[MarkCO]

Mark,

Which part(s) wear out our fall in the SLR blocks? It seems like a more robust system than most since it doesn't rely on a tiny spring.

Still has a protrusion into the gas stream. If you are looking for low use and willing the disassemble and clean every 200-300 rounds, the SLR is a decent choice. The Micro-MOA Govnuh is the one that I recommend if you want durable and adjustable. The Noveske SB is robust, but not really adjustable, just with a few settings.

Don't do it. Adjustable gas block will be more problematic (and expensive) than just running an H2 or H3 with a Tubbs flat wire buffer spring to balance out the overpressure.
