Buy the Vanguard.
I have owned the Zastava, and while a fine rifle built on the tried and true mauser 98 design, it is a bit "rough" [The roughness will polish out over time]
I have 3 - Vanguards, and I really like these rifles.
Well built, accurate and aesthetically pleasing.
BTW, I have also owned T3 rifles, and have none now.
You figure it out. lol.
Eagleye.
