All Vector AKs are built on U.S. made, NoDakSpud receivers or Global Receivers using the required U.S. parts to comply with 922r rules. Shipping for one gun is $20, UPS ground, unless otherwise noted or arranged. Due to confusion, we want to clarify that slant breaks on AKs are suppose to be at the 2 o'clock position, not straight up. This is the normal orientation. Standard thread on AK barrels is M14x1.0 left-hand thread. We parkerize our AKs unless otherwise stated. Due to diminishing supply of parts kits, we get them from where ever we can find them which might be from Poland, Hungry, Bulgaria, and even some East German kits. The country origin changes from time to time and we do not guarantee that your gun is from a particular country. We do not use Romanian parts kits. Our barrels are U.S. made, due to 922r and are normally not chrome-lined. There is an upcharge for chrome-lined barrels which at present is $20. It is true that chrome-lined barrels will last longer but it is our opinion that normally, a person would not wear out a barrel with normal shooting activity and the chrome-lining was used to protect against corrosive ammo which isn't around much any more.
