Southern Ballistic Research .240 Spectre

I noticed that SBR has recently added info to their website for what they call the .240 Spectre. It is basically a shortened 6.8 SPC case with a trendy long 6mm projectile that is optimized for short barrel AR’s using suppressors. They have brass already and will be providing AR uppers, receivers, etc… The ammo uses 6.8 SPC magazines in otherwise standard AR’s with the upper replaced.
