All Polish AK-47 receiver blanks from Keepshooting.com are manufactured at the Łucznik Arms Factory in Radom, Poland. As noted, these receiver blanks are 80 percent finished – presumably because the manufacturer wanted you to share some of the enjoyment characteristic of building an AK-47. Not really. Regardless, these receiver blanks are the perfect starting point for anyone looking to piece together the world's most iconic firearm.
The Polish AK-47 receiver blank is manufactured from normalized 4130 alloy steel, a material known for its applications in the arms industry due to its high tensile strength. Each blank features a thickness of .05 inches and is, as noted, already stamped and bent to appropriate dimensions that will provide for a precision build. Other prefabricated components include cutouts for the pistol grip screw, trigger and magazine well.
As the Polish AK-47 receiver blank is an 80-percent blank, some assembly is required, so to speak. Holes have yet to be drilled for the trunnions, axis pins and the selector switch. There are also no receiver rails included with this purchase. The blank is also "in the white," meaning that it has not been finished with any sort of treatment for resistance to corrosion, pitting or wear. But as everyone knows, Rome was not built in a day. This build will take some time and effort but the finished product will be all the more satisfying.
Do not fret. Finishing the Polish AK-47 receiver blank is a breeze with the purchase of some receiver rails and an AK-47 receiver template that provides detailed instructions on drilling holes that are correct and precise. These can both be found at a number of reputable Internet sources. The first step, however is ordering your receiver blank. Grab one today for the absurdly low price of just $22.95.
