A common question we get here at Scorpion Rifle Works, is "What are the common AR-15 platform Cartridge Choices?". The answer is, the most common AR-15 Cartridges are:
- 223 Remington
- 5.56x45mm
- 300 aac Blackout / 300 Whisper
- 6.5 Grendel
- 6.8 Remington SPC
- 458 Socom
- 50 Beowulf
With a simple swap of the barrel, the muzzle device and in some calibers the bolt, all of these calibers can be shot out of the AR-15 platform.
