You've already scratched the 5.56mm itch. Maybe you'd like a better big game cartridge, want to pursue long range shooting or are in need of a pistol caliber. I can definitely help you get there. Multiple calibers are available for the small AR platform including .22 LR, .300 Blackout, 7.62x39mm, 6.5 Grendel and many, many more. My large frame/.308 Win-sized ARs can be built in .243 Win, 6.5 Creedmoor, 7mm-08 and quite a few other chamberings. Options are available for complete pistols, rifles or uppers in just about any configuration.
