The VSKA SYNTHETIC comes to us as a unique addition to our family. Constructed with the same materials as the standard VSKA; an all-new bolt carrier, front trunnion, and feed ramp machined from S7 tool steel and uniquely heat treated for maximum durability. S7, often referred to as a “Shock-Resisting Tool Steel,” is commonly used for tools like chisels and jackhammer tips as it has maximum shock resistance and high compression strength, while retaining toughness. A carburized 4140 steel bolt, a chrome-moly 4150 barrel, and the RAK-1 Enhanced Trigger Group, are some of the standard features of this rifle; Uniquely sporting a Black Synthetic Polymer Stock and Fore-End, for a lighter-weight and a modern look!
