The BSF Barrels AR-15 .223 Wylde Barrel will require a 0.875" gas block. If you are looking for a standard low profile gas block, I would recommend the Aero Precision Low Profile Gas Block (linked below). If you want an adjustable gas block, I'd recommend the SLR Sentry 8 .875 Adjustable Gas Block (linked below).

Yes, these barrels have M4 feed ramps.
The manufacturer states that they've been holding sub-MOA along all their barrel lines.
