i have a bsa 4-16x44 mil-dot on my 308 and it works great! i have shot over 400 rds with it on the gun with out one single problem. and 150rds of match 178gn ammo. never a problem. my brother shot it twice with that scope then the next day he went to buy one for his 243.
i would rather have the scope than the r/c car any day. hope you enjoy your new scope
