The GLFA GL10 Semi-Automatic Centerfire Rifle may look like your standard AR-10, and it's even the same size - but its patent pending design packs a MUCH. BIGGER. PUNCH! The first caliber of the series, the .300 Win Mag, is a great long distance thumper, and the GLFA is now available in other great cartridges, for whatever your needs are. Solid, accurate, and able to go the distance, you can't afford to hunt without it!
