    Plodding forward slowly with a SBR build, Shopping for an 11.5" barrel and low profile adjustable gas block (Will be a dedicated suppressed gun with hand guard as close to or just up to the can). Many options out there, any recommendations, and reasons for your own choices?

    For a dedicated suppressed SBR, I would forgo the adjustable gas block and drill my own port size in the gas block. You'd get a block that was tuned for all the parts in your system, and you wouldn't have to worry about any adjustment screws or anything coming loose. Also, if you used a block like the one below: 'Baby Govnah', then you could pin it to your barrel so the gas block wouldn't come loose.

    It's only $30 too.

    On my Colt RR I had , it had the M4 Commando 11.5 upper on it. Ran like a top with the m4 2000 can on it. The upper was factory with a FSB.

    Now I got a Black Rain full auto lower I put together with a YHM 10.5 barrel, and a the adjustable gas block from Black Rain, and it's a nice set up. The adjustment screw has its own detent and will not back out.
