Timothy Lam does a two part video of the Tokyo Marui G36C NEG which is available in the markert for years now... "Normally, the Tokyo Marui G36c Recoil Shock comes with a metal top flat rail, 50 round magazine with fake bullets, stubby foregrip, stock with cheek riser/rest, rubber pistol grip, metal flashhider, and 3 long front handguard rails straight out of the box. However, I took all of these things off and installed a standard JG G36c top rail with the iron sights.
