The Stag 15 SPR Upper were 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. Featureing 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. 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.
* To prevent any confusion, the purchase of any Stag Arms Complete Upper does NOT include charging handle or BCG.
