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 polymer stock and polymer pistol grip complete the list of standard features. The RAK-74-P Polymer is a modern take on an AK-74 and will be ideal for the AK enthusiast. - CALIBER 5.45X39MM Soviet - MAGAZINE (1) magazine with 30rd capacity accepts Double Stacked AK-74 Magazines - BARREL 16.25" 4150 Nitride, threaded Metric 24x1.5, muzzle device - RECEIVERS Fully Heat Treated Mil-Spec Stamped Receiver - HANDGUARD Polymer Upper/Lower - SIGHTS Rear Sight (Adjustable for Elevation), Front Sight (Adjustable for Windage) - STOCK Polymer
