KJW MKI Full Metal Sniper Conversion Barrel Kit for KJW MK1-C, Black

The KJW MK1C Sniper Conversion Kit turns your KJW MK1 pistol into a longer-range option without swapping platforms. It adds an extended outer barrel and hop-up chamber to a pistol you're already carrying, giving you better accuracy at distance while keeping the compact footprint of a sidearm.

What the kit includes. You get a full metal barrel assembly and a hop-up chamber. The extended barrel improves air seal and gives the BB more time to stabilize, while the hop-up chamber lets you dial in backspin for flatter trajectories. Together they're what move the needle on consistency, not raw velocity.

Where this fits. This is for pistol players who need more than CQB range but don't want to carry a primary rifle. Think backup role on fields with 300–350 FPS indoor caps, or as a compact option when you need to move quickly between positions. It's not a DMR replacement and won't trade shots across an open field, but it does give you meaningful headroom over a stock pistol.

Before you buy. This is a parts kit, not a complete gun. It fits the KJW MK1-C platform only. You'll need to install it yourself or have a tech do it. Realistic range gains depend on hop-up tuning, BB weight, and air seal—expect solid improvement at 100–150 feet, not sniper distances. The outer barrel is metal, so the weight is noticeable compared to a stock pistol.
