The BUBAR10 Rifle 3D Printable

Quote:Preface
The BUBAR-10 is a 3D printable LR308-style lower receiver. It utilizes simple metal parts to greatly enhance the strength/durability of the lower – able to withstand pushup tests, drops, throws, kicks, and other hard abuse. At the core of its design is a U-Bolt to clamp the buffer tower down (preventing cracks), two humps to spread bending force at the rear of the receiver along the top deck of the lower, and two eye bolts to act as the front takedown lugs on the lower (which also help clamp the front of the lower together, enhancing strength further).
Note: While the BUBAR is a very strong lower, it is not advised to shoot it without its metal reinforcements – without these reinforcements, the lower will not prove strong or reliable.
This documentation will walk you through the process of building your own BUBAR lower – while many of the steps are standard to building out an AR15 lower, some fitting is required on the metal reinforcements for this lower, and some things are unique to this build due. Do not assume you know how to assemble your parts without reading the documentation!
