Use ball valves for everything else, even fixture stops. For hose hydrants, anti-freeze or even regular, use multi-turn.
Gate valves are a different animal, they work fine unless you need to get to a different job or it's 4pm on Friday.
now that I'm a Maine resident I'm supposed to get an out of state FID card but I'm not going to. I spend equal amount of time between the 2 states but my driver's license is for Maine. If I'm gonna buy a new gun I'm doing it up there where I don't need to buy something that's been neutered. Only disadvantage I think I while I'm in NJ is being able to buy handgun ammo in person, I can just drive 30 minutes to Easton and do that. I also know I can't bring any NFA items to NJ that aren't class 1's.
I never saw anything with such names on receiver and I use to serve Soviet Army long ago with AKM and many other AK style rifles. Vepr or Saiga is non-millitary firearms, banned for import but not for sale or owning in US. Personally I wouldn't build AK but just buy Wasr 10 and be happy, modify it as you like and legal in NJ.
