Which Caliber Would you Choose?

Which Caliber Would You Choose?  The F4 Small Frame AR10 gives you a ton of choices!

Do you hunt? How about .243 Remington or 7mm-08.  Do you compete in the Precision Rifle Series?  Then look at .308 Winchester, 6.5 Creedmoor, or even the badass and little known .22 Creedmoor that is an absolute burner.  Offering multiple calibers in the AR10 platform is nothing new, offering a wide range of calibers in a Small Frame AR10 is.  The F4 SF-10 AR15 sized from the magwell back; utilizing quite a few Mil-Spec AR15 parts.  And we make the lightest AR10 platform in the industry.  It’s not a skeletonized “Tacti-cool” rifle with Titanium parts; it was done by significantly reducing the size of the Receivers, Barrel Extension, and Bolt Carrier Group (BCG).

In just a few weeks we’ll be releasing our SF-10 in the following calibers and configurations:


  • .308 WinchesterF4 Defense F4X Small Frame 308
  • 6mm Creedmoor
  • 6.5 Creedmoor
  • .243 Winchester
  • .260 Remington
  • .22 Creedmoor
  • 7mm-08


  • .308 Winchester
  • 8.6 Creedmoor
  • .45 Raptor

Military and Law Enforcement:

  • .308 Winchester

Hunters, we have every game animal covered in North America.  Size and weight matters, when humping it through the mountains, forest, or desert.  The .243 Winchester and 7mm-08 have been a staple for large game hunting for a very long time.  The 7mm-08 now comes in a semi-automatic lightweight rifle. The 7mm projectile is very versatile and suitable for all of North America’s game animals, good ballistic performance and power enough to deliver knock down velocities over distance.

This medium capacity cartridge is the .308 Winchester necked down to the popular 7mm caliber. The 7mm-08 cartridge has the same powder capacity as the .308 Winchester, but it fires more narrow, higher B.C. projectiles in any given weight category, thus it shoots faster and flatter, drifts less in the wind and retains more energy downrange.

Predators, particularly coyotes, don’t stand a chance with the .22 Creedmoor sending an 80 grain Berger bullet downrange at 3600fps.  Lights out!

PRS, 3-Gun, and the various Sniper competitions; we’ve got your back.  You have a wide range of calibers to choose from; 6.5 Creedmoor, 6mm Creedmoor, .22 Creedmoor, .308 Win, .260 Remington…..in a 7.5lb rifle.

And our LE/MIL brothers.  It just makes sense that a 16” .308 Win that weighs 6.49lbs holds a significant advantage in tight spaces and on the move.  The large caliber stopping power, size and weight of an AR15, and versatility of a semi-automatic rifle…..again, it just makes sense!
