For those who want a lighter, handier SKS without touching the bolt or permanently modifying the rifle, the Nikai chassis is the answer.

Built around factory compatibility first, it runs with OEM fixed magazines, traditional duckbill detachable magazines, and includes a duckbill delete mag block in the box for those who want a cleaner reload setup without committing to permanent modifications.

No cutting. No welding. No irreversible gunsmithing.

The chassis is designed around PPA-CF for maximum rigidity, heat resistance, and impact durability while keeping overall weight low. Unlike brittle printed plastics or overly flexible polymer setups, PPA-CF gives the rifle a solid, duty-grade feel that holds up to recoil, field use, and harsh temperatures. If you’re building your own, most quality nylon carbon fiber filaments will also work.

Required hardware:

• 2x M4x8mm flathead screws (handguard)
• 2xM4x6mm brass-insets
• 1x 9mm OD x 25mm spring (trigger guard retention)
• 1xM5x25mm hex bolt (grip)
• 1xM5x10mm brass-inset (grip)

That’s it. Minimal hardware required.
