6mmAR: AR-10 Performance from an AR-15
by Robert Whitley, www.6mmAR.com

" The 6mmAR is an easy cartridge to make, just run 6.5 Grendel brass through a 6mmAR full-length sizing die to neck it down to 6mm. (I had Redding make a special run of custom full-length dies that give .004″ tension on un-turned brass). Then load your cases and off you go to the range"

6mmAR Basics

Case: Derived from parent 6.5 Grendel case. Uses Lapua Brass, with small primer pocket and small flash hole. Case capacity is 36.0 grains of water

6mmAR Match Uppers
Complete match rifle uppers (with 6mmAR bolt), ready to attach to your lower, are available from AR-X Enterprises, LLC.

" It's easy to set up an AR-15 for the 6mmAR cartridge because all rifle components (except barrel and bolt) are standard .223 AR-15 parts. Minimal modifications to the rifle are necessary to make an AR-15 function in 6mmAR trim."
