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.

Vise-held splined rod that locks the AR-15 barrel extension so barrels, muzzle devices, gas blocks and handguards can be torqued without stressing the upper receiver.

  • Engages barrel extension splines
  • Protects upper receiver
  • For 5.56/.223 AR-15/M4

Notes

The Geissele Reaction Rod® (5.56/.223) is compatible with the HK MR556 upper receiver.
