This is the exact same rifle set-up that Eric Blandford used in his IraqVeteran8888 field review of the AirForce Texan. In his own words, this set-up is diabolical! You'll get the .457 caliber AirForce Texan, the extra Picatinny/Weaver rails, the awesome Hawke Sidewinder 30 SF 4-16x50 (10x Half Mil IR Reticle) Rifle Scope, a locking bi-pod, and a 100 cu in carbon fiber tank that fills to 4,500 psi allowing for multiple refills of your new AirForce Texan, but small enough to take into the field on your first deer hunt with the AirForce Texan. This combo is exclusive to Airgun Depot, and the savings of getting this exclusive combo totals over $200! This exclusive kit includes: Premium Hawke Sidewinder 30 SF IR 4-16x50 & UTG Rings ($580 value), Air Venturi 100 cu in Carbon Fiber Air Tank & Fill Station ($399.99 value), Bipod with locking legs ($34.99 value), Three Picatinny Rail Adapters: x2 for scope, x1 for bi-pod ($119.99 value).
