V14 Batch 1, now ready for dispatch!

CNC machined, engraved and anodised.

Improve the gas efficiency, reliability, cycle speed and awesomeness of your KC-02! Half the weight of the standard bolt carrier!

Replace your broken bolt carrier or just simply upgrade.

All bolt carriers have the ROGUEWORX logo CNC engraved onto them at factory.

DO NOT ATTEMPT TO REMOVE THE SILVER HEX SCREW FROM THE BOTTOM. That is NOT how you remove the piston. Just push the pin out.

Please note: standard KC-02 charging handle may need to be slightly filed down to sit correctly with the RogueWorx bolt. Depends what version of KC-02 you have.

It's been almost 5 years since we updated the design of our first product - the mighty bolt carrier! V13 served us without fail since 2017, with over 700 of them sold. Many things have changed since then. It's time this veteran part changed too!

The V14 bolt carrier now features:

  • Easy disassembly/re-assembly. No more need for hammering that tough roll pin in and out when you want to take the piston and nozzle out of your bolt carrier. The V14 design now comes with a solid steel ground pin which is held in place by a ball-detent. Simply push the pin out the side using any 3mm tool such as a screwdriver or Allen key to disassemble, then push it back in to reassemble. The ball-detent clicks into place in seconds, no hammering required, making swift adjustments both painless and fast. 
  • Hammer Spur tail kicker. Back in 2016, we shortened the overall length of the bolt carrier in our quest for weight reduction without fully understanding the implications of that change. Obviously, the design was a roaring success as we haven't had a single faulty bolt carrier returned to us out of all ~700 made. But now, 5 years on, we can re-visit that decision with a much deeper understanding of the KC-02, especially the trigger mechanism, which was a scary place for us back then. Now, we understand that the timing of the striker lock release cam on the underside of the bolt carrier is specifically tuned to the length of the bolt carrier so that the hammer is fully reset before the gas supply from the magazine is cut off. In shortening the bolt carrier, we made the mechanism more dependant on the kinetic energy stored in the bolt carrier, which can be unreliable in certain conditions as friction losses play a large part in that area. By restoring the true length of the bolt carrier in the area where it pushes the hammer down, we can ensure the hammer clicks back into the reset position just as the striker lock is reset. TL:DR - the hammer spur should make the V14 bolt carrier cycle more reliably across all gas types and configurations of the KC-02.
  • CNC Engraving. What's better than a laser engraved logo? Well, CNC engraving of course! We're proud to display our name and logo on as many of our parts as possible, and having it permanently CNC engraved at the factory stage just looks super slick. We know some true milsim purists would prefer no visible markings, but you'd be surprised how subtle this new engraving is. It's certainly less visible than the white laser engraving we've previously used.
  • Refreshed design. Hindsight is a wonderful thing, so we've used this opportunity to tidy up some of the problem areas on the bolt carrier design to make the machined finish just a little bit neater, and make things fit together just that little bit better.

Please note the recessed grub screw for the ball detent is sealed into the bolt carrier and should not be adjusted by the user because we dont want you to lose the small screw, spring and ball in there!
