PSA Sabre-IC 6mm ARC 20-inch Long-Range Rifle with Proof Research Barrel

A 6mm ARC precision build on PSA's Sabre-IC ambi receiver set, which uses the ICAR magazine geometry the builder credits for reliable feeding. A 20-inch Proof Research stainless barrel with a Superlative Arms bleed-off gas block and JP FMOS carrier sits under a 15-inch Timber Creek carbon-fiber Enforcer rail. A Vortex Strike Eagle 5-25x56 on a Precision 34mm mount, a Geissele SD-E flat trigger and a Luth-AR MBA-3 stock set it up for distance, with sub-MOA groups at 100 yards reported so far.
