Re: 308 bolt rifle (Nemessis)
First Off...NICE RIFLE!!!! I have one myself that I lucked out on and picked up on the used market. I did not reload for my 308 barrel since I had a bunch of FGMM 168s sitting here. I ended up having a 260 barrel made up for mine, shooting 142smks. I absolutely love the 260, poor 308 barrel just sits there now.
I had Nemesis Arms make me a 20moa rail since the one that came with mine was 0 moa, I then added a NF UNIMOUNT (20moa built in) with a NF 3.5-15x50 npr-1. I have 97moa to the top and about 15moa to the bottom end from my zero.
Your going to love the system, and get the backpack it is actually pretty handy when heading to the range.
