With an impressive 40-round magazine capacity, light recoil, and
great penetration at close distances, the CMMG® FourSix™ is
here to reimagine the Personal Defense Weapon. Not only is the
FourSix the first AR chambered in 4.6x30mm, but it is also the first
4.6x30mm firearm ever released to the U.S. civilian market!
What is 4.6x30mm?
First introduced in 1999, the 4.6x30mm is known for its pairing with
the Heckler & Koch MP7. By design, the 4.6x30mm is a relatively
small and lightweight cartridge with minimal felt recoil meant to
compete with the 5.7x28mm.
Ballistically the 4.6x30mm round is very similar to the 5.7x28mm
round in the sense that it is a high velocity, flat shooting projectile
that has great penetration, but where the 4.6x30mm will hold an
advantage is in your pocketbook. Due to the difficult barrier of
entry for ammo manufacturers, the 5.7x28mm round currently
and will always cost more than the more affordable and easier to
manufacture 4.6x30mm round.
