Used Patriot Valley Arms Osprey prefit chambered in 6mm BR for ARC Nucleus/Archimedes - 26", 1:7.5 twist, M24 contour, 5/8x24 threads. Per original owner, 385 rounds fired & shot under 1/2" MOA with 30.2gr (Varget or XBR). I am the second owner, but ended up picking up a 6br barrel for my AI, so never got around to shooting this one.
