Why buy from B&B

Because you work directly with a family-run business that cares about getting it right.

B&B Firearms is built on faith, family, service, and real product knowledge. When you buy here, you are not supporting a giant corporation — you are working with a veteran-owned family business that values honesty, guidance, and doing right by people.

Self-timing 3-port brake; raised slanted ports above bore centerline cut ground blast and add downward compensation; linked port double expansion chamber. The hybrid top and side ports keep the muzzle down so you can watch your impacts, and the self-timing collar installs by hand. Built for lightweight hunting rifles, AR-15s, rimfire.

Fitment & notes

  • Two body profiles depending on thread pitch
  • M15x1 fits CZ 600 Alpha / Ergo / Trail metric-thread models only (CZ 600s can be M15x1 or 5/8-24, check yours)
