Intriguing. If I liked Beretta, I'd have my carbine selection made for me. The pistol and carbine share ammo and magazine commonality with each other, and you can get the carbine to match other models of Beretta handguns. But get all those firearms above, and a shotgun and .22, and you can call yourself 'covered.' All from one company.
But that rifle, the RX4 is interesting, and appeals to my lack of anything that fires .223. If I were to get a .223 rifle, now I have another option. As if I needed MORE .223 options. AR's, Mini-14, expensive high quality quasi ARs like SIGs offering, HKs, now this.
Looks like the RX4 takes standard NATO magazines. Good. It's styling is similar to the CX4, but it actually looks better on this platform. Plenty of places to mount sights, flashlights and tactical bottle openers.
The Ruger Mini-14 still holds my heart. It's like an M1 Carbine that fires more common .223 ammo and they still manufacture is quantity today. It has the Garand style action I love, and it's still all conservative in styling with wood stocks common. Less expensive than most alternatives, too. MBtGE loves Mini-14s, but he is also digging the RX4. Availabilty of regular capacity magazines is its drawback.
