The goal of Pioneer Arms has been to be able to introduce a very dependable Eastern Bloc quality AK rifle to the U.S. marketplace at a very affordable price point. With this new 7.62x39mm Under-fold Polymer Furniture AK Sporter, we think that they have again achieved that in spades, and have brought a truly remarkable product to the US Market. This beautiful semi-automatic version of the Polish AK-47 Rifle got its start at the Pioneer Arms factory in Radom Poland with the final U.S. compliance and finish being done here in the U.S. by Pioneer Arms U.S.A. The rifle possesses the original Military Spec Polish Receiver and Barrel and many of the original Com-Bloc characteristics that you would expect from a Polish-based military rifle. As an under-fold stock AK Sporter, this rifle has all of the same base features as the standard Polish 7.62x39mm AK- Sporter, and features a rugged and durable polymer forearm and handguard. The highly desirable Mil-Spec under-fold stock works off the push of a button and locks in place in both the extended and folded positions. In addition to the hugely popular under-fold stock, this rifle features a sling swivel, a new bolt hold open safety lever, and a black polymer AK pistol grip that closely matches the furniture. It also features the new Pioneer Arms - Premium Grade Hand Polished AK 47 Fire Control Group and an internal side retention plate for the ultimate smooth trigger feel. Unlike many of the U.S.-built Franken-Rifles on the market today, all of the primary rivet work, head spacing, etc... on this rifle is done at the factory in Poland so the fit and finish are exceptional. The Pioneer AK Sporter has the same primary receiver components, trunnion, and bolt carrier group as the select-fire rifles that Pioneer Arms produces to fulfill their numerous military contracts. In fact, this rifle incorporates the same front trunnion as all of the select-fire ( full auto ) AKs that they produce for military applications around the world. All structural parts have been rigorously tested to ensure the highest possible quality and long life. The barrel is threaded on the end with the original military 14x1 left-hand thread pattern and features a phenomenal Castle Compensator produced by Class 7 Depot, which features a recoil-reducing brake, and a spiked crown reminiscent of wire cutting surplus muzzle devices. Sights are meticulously inspected for proper alignment so you should expect no canting. Gas port settings are properly drilled to ensure smooth cycling action with no overblows or short cycles. Rivet work is triple inspected and each rifle leaves the plant with a high degree of uniformity from rifle to rifle. They are completed with a beautiful black melonite external finish.
