Knights Armament Corporation SR-15: A battle proven design gets major upgrades!
Roy Lin
The Knight's Armament Corporation SR-15 carbines feature some of the most advanced designs and materials ever used on an AR-15 style rifle, as well as a slew of upgrades!

Battle proven and continuously upgraded, the AR-15 rifle has served as a military, law enforcement, and civilian enthuisiast rifle for more than 50 years.  Given its reliability, accuracy, and modularity, it remains one of the most respected and used weapons in the world today... but there are elements of its design which are locked in place due to its widespread adaption.

Knight's Armament Corporation worked with the original designer of the AR-10, and one of the three engineers who designed the AR-15, Eugene Stoner, to create a "Stoner Rifle" which would be an evolutionary upgrade to the AR-15 rifle.

The first thing people noticed about the rifle is that it is fully ambidextrous, allowing left handed users to easily access their own safety lever, magazine release, and bolt release during normal firing.  The second thing that people noticed is that the rifle is light!  Despite having a cold hammer forged barrel, a full free floating aluminum quad rail and included iron sights... the rifle weighs only 6.70 pounds!  KAC was able to achieve this amazing lightweight by designing the rifle as a holistic system.

Subtle upgrades include a tuned gas system and buffer, as well as a completely redesigned bolt.  A normal AR15/M16 bolt is a wear item, and must be replaced at regular intervals as they will eventually break (5000 round internvals are recommended for critical military and police use, 10,0000 round intervals recommended for civilian use).   The SR-15's bolt has been completely re-engineered to increase comparable life expentecy depending on usage, to about 5 times that a normal bolt would experience.  The extractor has been beefed up, the extractor geometry has also been revised.

All in all, this rifle is a premium rifle in every sense, and though it costs much more than a standard AR-15 out of the gate, is well worth the extra expense for a hobbyist or professional looking for an excellent rifle.
