The Atom chassis fits my needs perfectly for a super lightweight rifle for calling predators. I usually sit on a stool, preferably with my back against a tree, and scan with a helmet mounted thermal. I want to sit comfortably with the rifle balanced on a tripod with my hands free to operate the remote and be ready to fold up the helmet mounted thermal to take aim with the thermal scope on the rifle.
I absolutely love the looks of the MgLite and MgMicro Lite in their respective XLR chassis! The Element 4.0 chassis on the Bergara MgLite was what first caught my attention and gave me the fever for a new rifle, but for 100 yards or so suppressed nighttime predator hunting, I didn't want the 22" barrel. The introduction of the MgMicro Lite with the Atom chassis and 18" barrel put me over the edge to actually make a purchase. It arrived at my FFL today and I am waiting for him to get back to his shop to go pick it up. I hope the chassis feels as good as it looks.
I have a Blaser R8 in 270 Winchester that shoots Hornady 130 grain CX bullets 0.5 MOA consistently, so I will probably skip the 6.5 PRC. But if I like the MgMicro Lite with the 18" barrel in 6.5 Creedmoor as much as I think I will, I would really like to have an MgLite with 22" barrel in 7 PRC.
