The heart of this classical rifle is the fully heat treated Stamped receiver. The design holds true to the original AK platform which started off as a stamped gun before the Russian military moved into milling and ultimately back to stamped. The barrel is made from 4150 steel which has been nitride and features a 24x1.5 right hand threaded barrel with a muzzle device installed. The polymer upper and lower hand guards with a folding stock and polymer pistol grip complete the list of standard features. The RAK-74-P-SP Polymer is a modern take on an AK-74 and will be ideal for the AK enthusiast. - CALIBER 5.45x39MM - MAGAZINE (1) 30rd capacity - BARREL 16" 4150 steel - MUZZLE 24x1.5MM RH w/brake - SIGHTS Front Adjustable Post, Rear Leaf - STOCK Folding
