The SR-15 E3 MOD 2 series 5.56mm NATO barrel is manufactured for military grade durability, and is free-floated inside a URX4 M-LOK handguard. An improved E3 round-lug bolt design both enhances function and increases bolt life far beyond the industry standard. The 5.56mm 3-Prong Flash Eliminator interferes with propellant gas combustion forward of the muzzle to significantly reduce flash signature, will not ring upon firing or when struck, and is compatible with the Knight’s line of 5.56mm QDC Signature Reduction Devices.

    Immediate shipping, excellent communication. Dylan is the man. Super responsive and excellent prices on top notch products. I can’t stress enough how pleased I am with my purchases from Stoner Tactical. I wish all dealers would follow his business model.

    Glad I discovered Stoner Tactical. Learned about Dylan and Stoner Tactical and purchased an 11.5 upper. Shipped the same day and delivered 3 days later. I will definitely be ordering from him in the future.
