NV is a game changer ,the only thing is it can become an obsession, i started off
one of the first Nite -site-NS-200,s and used that for 3 yrs with great success ,I now own a NS-wolf, a NS-Viper
a pard NV008 , a pulsar N750,and two nv addons built by two friends of mine,
so i have a few NV goodies I use these on rimfires, fac air & sub 12fpe airguns.
