M4 / AR-15 Lowers

The lower serialized part of the rifle that is deemed the “firearm” legally. Given how easy it is for anyone to assemble one, my general advice is just buy a stripped lower and customize it. However there are a few unique options provided by some companies that require you buy the lower complete, or near complete.  I intend to talk more about those options here as I get more time. In the meantime you can see refer to the list of AR makers

 

AXTS: for a truly ambidextrous lower

New Frontier: Polymer lower makes it the lightest cheapest and certainly weakest lower available.

Palmetto State Armory - cheap complete lowers and versatile LPK options.

SAA - cheap complete lowers
