Harvester Lightweight 280 Rem.


Price: $1,995





This is our Harvester Lightweight rifle based on the Remington 700 XCR II stainless steel rifle with black Trinyte rust-proof coating. The rifle is fully Accurized with aluminum pillar and glass bedded action, into a McMillan Remington Hunter stock in Edge Technology. This stock is similar to the Sako Hunter and has a nice palmswell in the grip. The stock is at standard length of pull with a 1" Pachmayr Decelerator recoil pad. Rifle weight is 6.5 pounds. The factory X-Mark Pro trigger is tuned to a crisp 3.0 pounds. Barrel break-in is done and the rifle shoots great. Three-shot groups measure .490" with Federal Premium 140 grain TSX ammo at 100 yards!
