The Laylax split receiver pin replaces the front body pin of the Tokyo Marui M4 series.
Once installed, the internal screw is tightened to lock the pin in place.
This also helps reduce any wobble between the upper and lower receivers.
Laylax NGRS Split Receiver Pin
Compatible with all TM M4 variants (SOCOM, CQBR, SOPMOD, RECCE) as well as the HK416 variants.
When installed in the HK416 variants, the left end of the pin will be slightly recessed in the receiver as it is around 2mm shorter than the standard body pin.
