This is the Desert Tech HDI Stock/Receiver kit only. This is a Black Receiver Black Stock FAST AND EASY CALIBER CONVERSION: The Hard Target Interdiction quickly converts between the following calibers: .50 BMG and .375 Cheytac. The conversion is simple and takes less than sixty seconds while still returning to zero. COMPACT & RUGGED: The Desert Tech HTI utilizes a bullpup configuration and collapsible bolt design. The compact design shifts the weight rearward, creating not only a shorter combat ready weapon, but also achieves better balance. The Desert Tech HTI was designed to operate reliably under the harshest conditions. It utilizes high-impact polymers, aircraft grade aluminum, ultra high-strength steel, and the strongest coatings on the market today. Stock panels surround operating components. The panels attach directly to the receiver which acts as a full length mounting chassis, eliminating the need for any sort of bedding. The HTI sustains its accuracy and reliability in virtually any environment: subzero temperatures, extreme heat and dust, to moisture of jungles.
