    I want to remove the front sight on my KWA KM4 Ris and I need to know what's the best gas block thing to buy for it. since I need something to hold the rail system back, if I'm wrong correct me. also there's a front sling adapter I want to keep on there, does it come off the front sight?
    thanks
