Inspired by the legendary Mk 12 Special Purpose Rifle, Stag Arms set out to design a useful and versatile rifle that offers today's AR-15 enthusiast all the utility of the Mk 12 in a modern package. Much like the original Special Purpose Rifle was designed for greater effective range than an M4 Carbine, the Stag SPR was designed to offer greater effective range over our shorter carbine and pistol offerings in the lightweight AR-15 platform without stepping up to the larger Stag 10. We started with a traditional 18" SPR profile barrel for reduced weight while maintaining rigidity and accuracy. Chambered in 5.56 NATO with a 1/7 twist rate and a rifle-length gas system, allows the shooter to use a wide variety of projectiles including the Mk 262 77gr Open Tip Match round originally developed for the SPR program. We include a Stag mil-spec, Magnetic Particle Inspected M16 bolt and carrier group that is Salt Bath Nitride (QPQ) treated for longevity and ease of cleaning. The extra long, free float Stag 16.5" Slimline handguard allows for increased accuracy, completely covers the low profile gas block and allows the user to customize their configuration to fit the mission with multiple M-Lok slots. The modern take on the traditional rifle is completed with a Magpul MOE Rifle Stock, MOE Pistol Grip, MOE Enhanced trigger guard, PMAG and an A2 flash hider to reduce signature in low light and no light operation.

Introduced in 1964, the 223 Remington is the civilian version of the 5.56x45mm NATO cartridge. Although very similar to the 222 Remington it has a slightly longer case and a shorter neck, giving it greater powder capacity and thus higher velocity--which was necessary to meet military penetration requirements at longer range. NOTE: 223 Remington ammunition may be safely fired in any 5.56x45mm chamber, but 5.56x45mm ammunition SHOULD NOT BE USED in a 223 chamber! Standard is a 55-grain bullet at 3240 feet per second, with lighter bullets somewhat faster and heavier bullets a bit slower. The 223 is the most popular 22 centerfire today, and possiby the most popular centerfire cartridge. Ammunition choices are legion, as are choices in firearms. The 223 is an accurate cartridge ideally suited for varmint hunting out to beyond 300 yards, and with heavy-bullet loads designed for the purpose is used effectively by many deer hunters. — Craig Boddington
