Has anyone seen Les Baer has came out with 2 new rifles. One is like the 6.5 Grendel, called the .263 LB custom and the other is the 6 x 45. The 6 x45 says it takes stand AR mags and is a 5.56 necked up to 6mm. Anyone have further info on these or thoughts? The .264 looks promising but, I hate that the only company that mags for them is C-products.
