INTRODUCTION

The SureFire Reinforcing Bar Cutter (RBC) is designed for breaching requirements when an 

operator needs to cut through reinforcing bar blocking entry. This product slides over the SureFire 

WARCOMP 556 CTN adapter and securely attaches to the adapter for rock-solid mounting via 

the same patented Fast-Attach

®

 mechanism used on the SOCOM Suppressor Series. Cutting 

through rebar with live ammunition is inherently a dangerous situation; however, the RBC 

provides a more effective, safer option by aligning the bore of the weapon with the rebar and 

redirecting the majority of spalling from the fired round and rebar fragments away from the 

shooter. Simply index the RBC with the rebar and apply forward pressure while firing the weapon. 
The RBC will not degrade performance of the weapon or adversely affect ballistics.

ATTACHMENT

1.  Depress Fast-Attach

®

 mechanism latch and rotate the locking ring ½ turn 

counterclockwise to unlock.

2.  Slide RBC over the WARCOMP 5.56 CTN Suppressor Adapter.

3.  Rotate RBC until the indexing slot lines up and seats onto the suppressor adapter 

indexing tab (Fig. 1).

4.  Tighten locking ring by rotating clockwise until rotation stops.

 

Note: Audible clicks should be heard when tightening locking ring.

5.  Verify RBC is securely attached by attempting to rotate while pulling away from the 

weapon system; only slight rotational movement under tension should be felt with 

the RBC remaining firmly in place.

 

Note: When attached correctly, the RBC will have no forward movement and minimal 

rotational movement under tension. 

REMOVAL

1.  Depress Fast-Attach

®

 latch and rotate locking ring ½ turn counterclockwise.
