In today's episode of TFB's Behind the Gun Podcast, we're bringing back TFB Writer Darwin to talk about the new SIG MCX-SPEAR otherwise known by its military designation - the XM7. The XM7 is the result of the NGSW program and I've recently had the opportunity to start digging into one of their Civilian versions of the rifle chambered in the new 6.8x51mm hybrid cased ammunition. Darwin is quite a fan of not only SIG's new rifle but also battle rifles in general. Today he and I will discuss some of the history of the XM7, and talk in depth about the new 6.8x51mm cartridge and some of the potential it might have even outside of combat. Please welcome back TFB Writer Darwin to the Show!
