If you want an 80% AR-15 lower for as low as $65, you might want to check out a new crowd sourced project from Fealty Arms. The new company is using RocketHub to acquire funding, and offering backers a variety of non-regulated 80% lowers in exchange.
An 80% lower is essentially the start of a “from scratch” rifle. Since it is not complete, it is not regulated by the US government as a firearm. There are no serial numbers, dealers or other hoops to jump through. They can be mailed directly to your residence – just like any other piece of metal.
An 80% lower is not something you can just drop a trigger kit into and slap on an upper to make a functioning AR-15, however. The lower will still require a fair amount of work with a drill press to turn it into a useable lower.
It may not be quite as intense as building an AK-47 from a shovel, but these lowers will definitely add a little complexity to the relatively simple process of assembling an AR from parts. The funding period for Fealty Arms runs through April 30.
