Try Polymer80. This may be the most efficient way to learn how your AR pattern rifle works. The lowers are classified as 80% complete, which means you don&#8217;t have to treat them as firearms. They can be shipped to your house. You don&#8217;t record their serial numbers on any 4473, or any other form. It is not yet a firearm.<\/p>\n<p>With a little bit of elbow grease, and the help of a drillpress or milling machine, they can become viable firearms. Cutting them is easy enough. Polymer is much easier on tools than aluminum (which some 80% lowers are made of). After cutting pockets for a few of the internals, the new receivers can be fitted to AR uppers (which are also not considered firearms) to form working rifles.<\/p>\n<p>Ploymer80 began with AR-15 blanks and has since expanded to include polymer .308 lowers. The ones we saw at SHOT Show look good. They come with detailed instructions, a drilling jig to help guide the process, and the black polymer lower blank.<\/p>\n<p>My question about the use of polymer had more to do with the longevity of the material than the cutting process. The crew at Ploymer80 said they&#8217;d gotten great results from their polymer. Its elasticity allows it more flex than aluminum, which means it can take the abuse of recoil without developing stress cracks.<\/p>\n<p>We&#8217;ll have on in house ASAP, and will chronicle the process.
