Have had several phone calls and people looking for reviews on these rifles...Small Arms Magazine and Guns and Weapons for Law Enforcement Magazine recently did independent reviews on the CORE 15 rifle systems. They break down the rifle with respect to accuracy, fit and finish, parts/internals and overall value. They also did some extensive range testing too...
Check them out here:

We will also have a range review up pretty quick!
