Custom KC-02 Builds Report - Carbon Hogue #02 and #03

Well, it's been a long journey to get these 2 more additions to our Carbon Hogue line finished! Roughly a year and a half as they started in late 2023!

Following on from the original CH#01 we built for Silly Ghillie a couple years ago, this pair CH#02 and CH#03 unfortunately ran into the cold, bad weather of winter in November 2024 before we were able to properly test them so we were limited in how much we could test them until recently when the UK got some very welcome warm weather in April and May 2025.

The goals for these 2 builds were the same as before - as light as possible, with extreme long range accuracy.

Parts list:

• Base gun - KJW KC-02 V1
• Stock - Hogue Overmold rubberised stock - imported from USA
• Outer barrel - PPT (Project Precision Turning) 430mm Carbon barrel with machined Gun-Metal Grey anodised fittings. These were made to order and took about a year to arrive.
• Inner barrel - EDGI stainless steel 430mm 6.01 VSR barrel, made to order.
• Hop rubber - Flamingo 50deg
• Trigger upgrades - RW Fang adjustable CNC trigger and RW Judgement hardened steel hammer and sear. Had to wait for a batch of these to be made in mid-2024.
• Hop unit - RW Genesis kit (flat purple hop key)
• Bolt carrier (lever-action) - RW Solid-State Bolt
• Bolt carrier (semi-auto) - RW V14 CNC bolt carrier
• Piston (semi-auto) - RW V3 CNC piston
• Nozzle (semi-auto) - RW Genesis CNC nozzle
• Rocket valve (semi-auto) - RW Apollo V4 NPAS valve
• Charging handle (semi-auto) - RW Talon handle
• Charging handle (lever-action) - RW HOM Underlever kit
• Mag release - RW Sickle mag release lever
• Rail system - RW Master Precision CNC rail
• V-block barrel clamp - RW 304 steel CNC V-block
• Inner barrel clamp - RW brass CNC Projnut
• Muzzle brake - RW Twister
• Bolt stop - RW hardened steel CNC bolt stop
• Buffer pin - RW silent PTFE buffer pin
• Gun Case - Plano Pillarlock 1511 hard case

Testing and final results

Final results - 70% hit accuracy at 71m when using 0.48g ammo at 2.5j on a breezy day in a farmers field!

Build Progress pics

Arrival of the base guns from UK wholesaler, and the Hogue stocks from Brownells from the USA.

They look like this for about 12 seconds in my hands....

Removing rear receiver tangs with the bandsaw

Installing steel thread helicoils in the receivers for strength

Respraying the receivers, 3 coats of satin black hammerite

Rear tangs all gone, steel threads installed, paint jobs complete on the 2 far ones

Modifying the Hogue stocks to suit the airsoft receivers

Fits like a glove!

Stripping the trigger mechs down for several days of cleaning, polishing, adjusting...

Polishing key parts of the trigger mech

Perfect re-assembly, always keeping them paired with their receivers

The PPT Carbon barrels finally arrive! Damn, they're sexy! And weigh almost nothing!

The EDGI custom steel inner barrels arrive

Perfecting the hop rubber alignment in the barrels

The most important part of assembly - getting the barrel and rail perfectly attached to the receiver, everything straight and balanced on the clamps. Look at all the tools around me...

Perfection, ready to install and begin testing!

When installing in a Hogue stock, you hook the trigger mech in first then squeeze the front of the rail on the barrel until it snaps down into place

Both assembled and underlevers installed

Beginning the indoor testing to bed in the parts

More indoor testing through the winter

Gotta have scopes that are up to the task for high-precision shooting at 80m+ away

Winter testing for gas guns is very hard

Finally, some weather warm enough and calm enough for a proper 8-hour test session outdoors

71m target

Setup on the fence, jacket and bipod for support. Notice the phone in the holder for the zoom video!

When the guns can land multiple hits in a row on torso and head-size targets at 70 - 80m with predictable hop response and very few fliers, they are finally ready for customers.

We will not ship the guns out until they perform well enough to meet our standard. 70% hits at long range! Even with a breeze! It's very impressive for an airsoft gun.
