Grendel-based 6mmAR Cartridge for High Power

A full-time lawyer, Robert Whitley is also an avid prone, Highpower, and cross-course shooter. Over the past two years, Robert has pioneered a cartridge for these disciplines (as well as long-range varminting) based on the 6.5mm Grendel necked down to 6mm. Robert calls the cartridge the “6mmAR”.

The 6mmAR cartridge has performed very well in AR-based comp guns, both with shorter bullets loaded to mag length, and 105-107gr bullets single-loaded. Robert has complete info about the 6mmAR on his website,, including recommended loads and field test results. Robert has also developed a higher capacity version, with the shoulder blown forward and a shorter neck. He calls this the 6mmAR Turbo. This round can drive 105-108gr bullets in the 2850-2900 range, and it has proven very accurate. It is one of the best options for AR-platform space-gun shooters.

6mmAR brass 6mmAR turbo

Though making 6mmAR brass from 6.5 Grendel brass is quite straight-forward and simple, Robert receives many questions about forming the brass, so he recently prepared a video. The two-minute video shows how quick and easy the brass-forming process can be:

Robert also builds and sells products for across-the-course shooters, including complete AR uppers, chambered in a variety of calibers, including 6mmAR. Jerry Tierney, 2005 NBRSA 1000-yard champion, has a 6mmAR upper built by Robert and Jerry says the upper “Absolutely shoots great. I love it.” In the past few months, Jerry has broken many NRA senior records with his new 6mmAR-chambered rifle.

NEW Product: Multi-Function Gun Tool Introduced

Avid Design has released a new multi-tool designed expressly for rifles and shotguns. The $24.99 Gun Tool combines 18 of the most commonly used long gun tools in a compact package. The Gun Tool boasts three Torx wrenches (T20; T15; T10), two Allen hex drives (3/32″; 5/32″), and four screwdriver blades (1/8″ flat; 3/16″ flat; Phillips 1 & 2). In addition, there is a magnetic 3/16″ driver, a pin punch, and a stainless claw blade useful for opening shipping boxes or trimming target backers.

The most unique feature of the Gun Tool is a stepped, multi-size choke-tube wrench that fits six shotgun bores from .410 all the way up to 10 gauge. For active shotgunners, that provides great versatility in a small package.

The Gun Tool

Respected gun writer Jim Shepard has reviewed the Gun Tool: “I can honestly say that I’ve been playing with ‘The Gun Tool’ for a couple of days, and I’ve found it to be a pretty promising device that really should find a place in lots of range bags. If you’re a long gun shooter, it has something you’ll eventually need in the way of a tightening/loosening/adjusting tool.” Jim cautions, however, that the claw blade does not lock into place.

Currently, the Gun Tool can be purchased online for $24.99. NOTE: With each Gun Tool you get a FREE set of polycarbonate shooting glasses, complete with handy, lanyard-attached 26 NRR ear plugs. We figure the shooting glasses and plugs are worth at least $6.00, making the Gun Tool a pretty good deal at $24.99. And if you purchase two Gun Tools you get free shipping.
