JXAirsoft curates selected airsoft accessories for KS1 and L403A1-inspired replica builds, including the Angry Gun KAC-style QDC/MCQ-PRT and 5KU KAC-style QDC/CRS-PRT mock suppressors, 14mm CCW muzzle setups and optic accessories for modern rifle profiles.

TANGO6T-style LPVO option

For a KS1 or L403A1-inspired airsoft build, the bronze/FDE-style finish of the Holy Warrior TANGO6T 1-6x24 airsoft LPVO complements the tan and dark components commonly used across the rifle. Its 1-6x24 format adds a compact modern LPVO profile, with low-power viewing and variable magnification for longer airsoft sight lines.

KS1 suppressor options: short vs long

These two bronze KAC-style airsoft mock suppressors create different KS1 / L403A1-inspired front-end profiles. Choose the compact MCQ-PRT shape for a shorter setup, or the 163mm CRS-PRT when you prefer a more extended silhouette.

Short: Angry Gun QDC/MCQ-PRT

The compact MCQ-PRT profile keeps the front end visually shorter and less extended. Its bronze finish works naturally with tan furniture and the TANGO6T-style optic shown above. It uses compatible 14mm CCW airsoft fitment with QD-style muzzle parts as supplied.

Long: 5KU QDC/CRS-PRT - 163mm

5KU bronze QDC CRS-PRT long 163mm airsoft mock suppressor for KS1 and L403A1-style builds

The 163mm CRS-PRT provides the longer, fuller profile for a more extended KS1 or L403A1-inspired build. The bronze finish coordinates with mixed tan and black components, while the 14mm CCW fitment suits compatible airsoft barrels. Check muzzle and handguard clearance before ordering.

14mm CCW airsoft compatibility

Most airsoft rifles use 14mm CCW muzzle threads, but fitment can vary by brand, flash hider and adapter. Always check your replica's thread direction and muzzle device before ordering a mock suppressor.
