The FN SCAR 17 Gen 2 has arrived, and it brings several updates to the rifle platform and Classic Firearms takes a look at one. Key changes include a more comfortable UGG boot stock and a new handguard that offers extra space for accessories while helping the barrel cool down. For the handful of left-handed shooters out there, the addition of fully ambidextrous controls means you no longer have to perform gymnastics just to release the magazine or catch the bolt.
