Like how accurate? Can you do your part? What is this going to be? A bench gun? A battle rifle? Your not giving up enough info for us to help.
I have a mod 1 mk214. Good rifle, MOA shooter I would guess. I shoot it with a red dot and can hold 1.5 moa at 100, 5 shot strings. Good enough for me and what I need.
I have a 20" LaRue that shoots 3/8 moa at 100/5 shots, scoped, and I wouldn't want that to be a main battle weapon.
See where I'm going?
