I just completed my A2 build this AM. Haven't mounted the optics yet as I have not decided what to use. Thinking about the Shepherd P2 but don't know anyone who has one or a local dealer where I can fondle one! Anyway, here are the specs on the build.
Rock River Arms lower-stripped
M&A upper varmint kit: 20" hvy stainless bbl w/1 in 8 twist
RRA 2 stage NM trigger
Yet to be installed are the optics and a stock extension kit as the standard is too short for me. Build was pretty simple with the addition of a couple of tools I made on the lathe to make spring/retainer installation easier. Those little retainers for the pivot and takedown pins go a long ways when they get away from you!! Not someting you have to have but it sure makes things easier-especially if you have old hands like me. Will try and post pics when I get a chance.
brownells sales the pivot pin instalation tool for a buck or two. They are life savers.
I cant wait to see the pictures.
