This rifle is the newest incarnation of the wildly popular AR-50 chambered for the powerful .50BMG cartridge - a single-shot bolt-action rifle featuring a unique octagonal receiver bedded down into a V-shaped stock. Designed to be an economical answer for the challenges of long range shooting the AR-50A1 is amazingly accurate and with its massive muzzle brake it has a very manageable recoil. The AR-50A1 is a highly refined rifle which is a stark and refreshing difference that maintains its superiority over the competition. The buttstock is removable allowing for increased portability when traveling. Includes the extremely rugged and versatile GG&G bipod.Specifications: PRODUCT LINE: AR-50 PRODUCT CATEGORY: Bolt-Action CALIBER: .50BMG BARREL: HB Chrome Moly BARREL LENGTH: 30" TWIST RATE: 1:15 RH MUZZLE DEVICE: Multi-Flute Recoil Check FRONT SIGHT BASE: Modified Octagonal Form Grilled and Slotted for MIL-STD 1913 Scope Rail With Boss to Engage Cross-Slot on Receiver STOCK: 3-Section - Extruded Forend Machined Grip with Vertical Grip Removable Buttstock BOLT: Triple Front Locking Lug EJECTOR: Spring Loaded Plunger Auto-Ejection EXTRACTOR: Sako Type TRIGGER: Shilen Standard Single Stage Approximately 5lb FINISH: Hard Anodized Aluminum Manganese Phosphated Steel OVERALL LENGTH: 49.8" Collapsed | 58.5" Extended WEIGHT: 34.1lbs INCLUDED: 15-Minute Sight Base Ear Plugs Owner's Manual WARRANTY: Limited Lifetime Warranty
