Developed by Eugene Stoner, This rifle exhibits some of the characteristics of his former designs, notably the AR-10 and the M-16. However, this is not just an upgraded assault rifle, but was designed from the beginning as a sniper rifle. There has been mixed results about this rifle. Some people swear by them, and others do not like them at all. (The 1st SFG comes to mind here). The accuracy has never been an issue, they all tend to be VERY accurate, with .5 MOA attainable. But the reliability during field operations has been questionable. If you decide to go with one of these rifles, you will need to maintain a very tight maintenance schedule to insure reliability, and prolonged field operations will require very close attention. The SR-25 is manufactured by Knights Armament Company (KAC). 

Over time, KAC has further developed, enhanced, and modified the SR-25 into more reliable and modernized versions of the SR-25, such as the M110 for the US Army and the Mk11 Mod0 for the Navy SEALs. But they all have their roots traced back to the original Stoner design.

I have an SR25 With a 24” bull barrel match grade manufactured 9-13-2001 . The serial number is K10361 .

The serial numbers usually begin with a 1of a 2 this is the only K I’ve ever come across .

So were there only so many of these made ?
Any information would be appreciated thank you .

Also does that make it a rare SR 25 it shoots like a dream well over 1000 yards


Not sure on the serial number, might not hurt to give KAC a call and ask. They made a good number of them and they still make a few different variants. There is some collector value, but not huge yet.
