Will the Hard Charger work on 300 Blackout, 6.5 Grendel, 6.8 SPC, or 9mm and other pistol calibers?
Yes. The Hard Charger will work on any caliber as long as the upper receiver is a standard forged upper and the charging handle size is standard as it would be for a .223/5.56.
Will optics with large mounting knobs work with the Hard Charger?
In most cases, Yes. Optics such as Aimpoint Pro, ACOG, and many others, with the large mounting knobs, have mounts that are reversible (usually a couple screws on the underside). Switch the knob to the ejection port side (*this will not interfere with the case ejection) and they will work great together.
