Description
You’re on a ridgeline, glassing a valley at 600 yards. The wind is shifting, and the target is a steel plate, not paper. When precision at distance is the mission, and compromise isn’t an option, you need a rifle built for that reality. This is where the purpose-built engineering of the Knights Armament SR-25 E2 APR Rifle, .308 Win, 20″, 20rd, Black, M-LOK Rail separates itself from the pack. It’s a direct-impingement, semi-automatic precision rifle designed for consistent, repeatable accuracy with the power and reach of the .308 Winchester cartridge.
Here’s the thing—this isn’t a collection of premium parts assembled on a standard lower. The SR-25 E2 APR (Adaptive Precision Rifle) is a complete, integrated weapons system from one of the most respected names in military and tactical firearms. The 20-inch chrome-lined barrel provides optimal velocity for the .308 round, balancing length for ballistic performance with maneuverability. Weighing in at approximately 10.5 lbs unloaded, it’s built for stability, not for hiking light. The heart of the system is the enhanced SR-25 upper and lower receiver set, machined to tighter tolerances than a typical AR-10 platform. This foundational precision means it’s drop-in ready for serious work; no gunsmithing required to achieve sub-MOA performance with quality match ammunition.
The rifle’s 13.5-inch M-LOK handguard offers a clean, lightweight interface for mounting modern accessories like bipods, lights, and laser aiming devices. Its slim profile gives you a positive grip and allows for direct attachment of M-LOK panels or rails exactly where you need them. The system is designed for reliability with a robust bolt carrier group and an adjustable gas block, letting you tune the rifle to run smoothly with or without a suppressor. It feeds from reliable 20-round SR-25 pattern magazines, ensuring compatibility with a proven standard. At $5263.99, you’re investing in a legacy of proven performance, not just a label.

Frequently Asked Questions
Q: Is this compatible with my DPMS pattern AR-10 parts and magazines?
A: No, it is not. The Knights Armament SR-25 uses its own established pattern for receivers and magazines. You must use SR-25 pattern magazines, like those from Knights Armament or compatible manufacturers like Lancer Systems, for reliable function.
Q: Is the muzzle device removable for a suppressor?
A: Yes. The rifle features a standard threaded muzzle (5/8×24) with a factory flash hider. This can be removed by a qualified gunsmith to direct-thread a .30 caliber suppressor or attach a proprietary muzzle device. Remember, an FFL transfer is required for firearm purchases.
Q: Does it come with iron sights or an optic?
A: It does not. The SR-25 E2 APR is sold as a complete rifle ready for you to configure with your preferred optic, mount, and backup sights. The flat-top upper receiver is machined to accept any standard Picatinny-scope mount or red dot.
