UBAR2 Printable AR-15 Lower

about

The UBAR2 is the next iteration in the Vanguard series of printable AR-15 lowers and the direct descendent of Ivan’s U-Bolt Vanguard lower. Like the U-Bolt Vanguard, the UBAR uses a U-bolt to reinforce the buffer tower, but new to the UBAR is the use of rod-end eye bolts to reinforce the front takedown lugs. At time of release, these innovations make the UBAR possibly the strongest printable AR-15 lower.

The data package contains four different versions of the lower - two high shelf versions and two low shelf versions, each of which come with either a forward assist or no forward assist. This variety allows the lower to be used with many different AR builds.

As with all designs from IvanTheTroll the UBAR includes deeply detailed documentation to assist with printing and assembly.
