The Laylax receiver pin holds the upper and lower receivers together securely and features a locking o-ring instead of a c-clip. 
This ensures the pin can never snag in the receivers, rendering the gun unopenable. 

This pin is CNC machined from a much stronger material than the original and has a hard wearing satin-black finish.

  • Please take care when removing the original pin. 
    This pin is compatible with all Tokyo Marui M4 variants (SOCOM, CQBR, SOPMOD & RECCE) and while it will fit in the HK416 variants, the Laylax HK416 pin is a much better fit for those.
