This is a build currently being used for professional animal eradication…user has year-round permit to eliminate nuisance deer on a vineyard located somewhere in the Southern U.S. The gun is also killing lots and lots of coyotes.
The build has proven to be be incredibly accurate and reliable, shooting sub minute, .5 MOA with handloaded 5.56. The basic components are a Dirty Bird Industries Receiver set (https://dirtybirdusa.com)
an Odin Works BCG, and a 14.5" Faxon flame fluted match barrel. (pin & weld)
For the cost and performance it offers, this is a very, very hard combination to beat.
Optic of choice is an N-Vision HALO 25mm Thermal.
