Tactical Rifles’ SPG (Special Purpose Grendel)—shown here with the NightForce NXS 5.5-22x50mm scope, GG&G quick-detach mount, ARMS solid aluminum rail system, MagPul adjustable stock, SureFire muzzle brake, and Harris bipod— is designed specifically to optimize the efficiency and effectiveness of the high-performance the 6.5 Grendel round.

Projectiles in 6.5mm are renowned for their high ballistic coefficient. Benchrest shooters have embraced this chambering for decades in the large, heavy, bolt-action rifles. That’s nice, but what about the folks using semi-automatic, self-loading rifles? Alexander Arms offered a solution by introducing their 6.5mm version called the 6.5 Grendel in 2003.

Since that time, a few large ammunition manufacturers have produced factory loads in that chambering. The load was out there but didn’t really catch fire until more recently, when Hornady Manufacturing released their version loaded with a 123-grain A-MAX bullet.

This review actually began in earnest during the summer of 2010. The guys at Tactical Rifles loaned me one of their new Tactical SPG (Special Purpose Grendel) rifles. I secured some of the tough-to-find 6.5 Grendel ammunition from the few manufacturers producing it.

The 6.5mm or .264 chambering for the AR platform certainly has a tremendous amount of potential, with the rounds having the long distance accuracy of match-grade .308 but the felt recoil of the .223.

The Magpul PRS offers a fine-tuned, customized feel with an adjustable cheekrest and length-of-pull.
