30 REMINGTON AR
The 30 Remington AR was developed to bridge the gap between the 223 Rem and larger rounds like the 308 Win. As promising a concept as that may sound, the 30 Rem AR was a commercial flop and has never been manufactured by any company other than Remington. This round usually launches a 125 grain projectile out of a 24” barrel at a velocity of 2,800 fps. You can change those numbers around if you handload – and you should handload, if you want to fire any serious quantity of 30 Rem AR ammo.
