Just recently completed an AR15 in 6mm ARC. Got a 16" Rosco barrel, Odin works adjustable gas block, Aero Precision enhanced upper, JAG composites 15" bertha handguard on a PSA lower with a Geissele SSA-E trigger and magpul PR MOE stock. Has a Discoveryopt 5-25x56 ED PRS2 scope on a 20moa Discoveryopt cantilever scope mount. I just got approved for a suppressor and am picking up an Otter Creek Polonium Saturday. I have a 6.5 grendel AR, but am wanting to get into long range with a more compact AR15
