OK, gotcha. So... what is the 6.5 round that is currently available in the AR kits and conversions? A friend whom is a rather good engineer is also impressed with the 6.5.

Thanks.

There’s the 6.5 Grendel, which is a private-sector effort by Alexander Arms to fit a 6.5mm round into the M-16 platform.

6.5 caliber or .264 also called a 260 remington, has been around since the crack of dawn. neck up a 243 or neck down 308, you have a 260. First used by the US military before the Japanese adapted it in WWII nothing new about he 6.5.
