The Bergara HMR Pro has the gray stock and a TriggerTech trigger (it's a single stage, it's quite light, very crisp, no creep... at least mine is). The HMR Pro also has a better barrel, the Premier action (which is as good as any custom I've come across in smoothness), and is made in Georgia.
The Bergara B14 HMR is the same stock, yes, but a different color (tan) and has a standard Bergara trigger. Made in Spain, I believe.
