Why Knights Armament

Knight's Armament is the Titusville, Florida outfit that worked with Eugene Stoner on the SR-25. SOCOM adopted it in May 2000 as the Mk 11 Mod 0, and it later became the Army's M110.

Today's SR-25 comes as the CC and PC carbines on 16 inch barrels and the PR on a 20 inch. All use hammer forged, chrome lined 1:10 barrels, an E2 bolt with dual ejectors and ambi controls. Carbines run just under $5,000.

On the parts side, KAC's RIS and RAS rails are part of the SOPMOD M4 kit, and it also makes suppressors and night vision sights.

Expect to pay well over the typical part: about $2,090 for an upper against roughly $400, $1,000 for a lower against $213, and $1,280 for a suppressor against $900.

Then there's finding one. In early October only about 13% of KAC listings across stores were in stock, so a lot of it is wait and watch.

We'd buy KAC if you want the real military pattern rifle and can wait. For a working AR-10, you'll spend far less elsewhere.
