The SR-25 E2 series of rifles is the end result of decades of improvement and refinement to the AR-10 type rifle. While each model is oriented to an application, they all share high reliability, long critical part life and intuitive ambidextrous controls. Tested to and validated by the harshest combat conditions, they prove to perform as required. Barrel and bolt life are significantly increased, reducing the need for part replacement and extending maintenance cycles. An ambidextrous bolt release, selector and magazine release offer the left-handed user the ergonomic advantages inherent to AR-15 based controls, as well as giving right-handed users alternate methods of manipulation to increase efficiency of movement. (options may vary based on model)

  • 2 STAGE MATCH TRIGGER
  • MULTI LUG IMPROVED E2 BOLT
  • 5R CUT RIFLED BARREL

The SR-15 E3 Mod 2 line represents the pinnacle of the unique and revolutionary Stoner-designed operating system. The Mod 2 line features a proprietary mid-length gas system that increases reliability and durability, while also reducing felt recoil. This minimizes leakage, ensuring more consistent operation in harsh conditions, with or without an attached sound suppressor. The Mod 2 gas block is secured with a locking ring, which results in a more rigid barrel due to the elimination of taper pin grooves. This removes the need for individually fit gas blocks.An improved E3 round-lug bolt design enhances function and increases bolt life far beyond the industry standard. The URX4 handguard reduces weight through use of negative-space mounting systems and an integral barrel nut. An ambidextrous bolt release, selector and magazine release offer left-handed users the ergonomic advantages inherent to AR-15 based controls, as well as giving right-handed users alternative methods of manipulation to increase efficiency of movement.

  • AMBIDEXTROUS CONTROLS
  • 5R CUT RIFLED BARREL
  • M-LOK MOUNTING SYSTEM
  • 2 STAGE MATCH TRIGGER

The SR-30 takes advantage of the .300BLK cartridge, enabling a 9.5” barrel to be as capable as an 11.5” 5.56mm SBR. The Mod 2 gas block is secured with a locking ring, which results in a more rigid barrel due to the elimination of taper pin grooves, and removes the need for individually ­ fit gas blocks. An improved E3 round-lug bolt design enhances function and increases bolt life far beyond the industry standard.
