Picking the CMMG Dissent Br4 5.56mm NATO Semi-Automatic Rifle is easy, but choosing the right caliber to add to your safe will be a challenge. If you're leaning towards the tried and true 5.56mm, you won't do wrong with the 14.5" P&W Br4. Although the barrel is 14.5" the ZEROED SVD muzzle brake is pinned & welded to the muzzle, bringing the barrel's OAL to 16.1" which means no NFA tax stamp is needed as well as being in one of the best-looking rifles in its class.
