Knight's Armament SR-25 Precision Carbine 16"

The Knight's Armament SR-25 is the rifle that defined the modern 7.62 gas gun. Eugene Stoner's SR-25 became the basis for the U.S. military's Mk 11 and later M110 sniper systems, and the SR-25/DPMS pattern magazine that nearly every other rifle in this guide uses is named after it. When buyers ask which AR-10 the military uses, the SR-25 family is the answer.

The Precision Carbine pairs a 16-inch 5R, mid-weight, 1:10 chrome-lined barrel with a 15-inch URX4 M-LOK handguard, ambidextrous lower, and Knight's two-stage trigger. It feeds from any current standard AR-10 pattern magazine. KAC's chrome-lined and 5R barrels, E2 lugged barrel extension, and obsessive QC give it the strongest reliability reputation in the segment alongside LMT.

This is a halo rifle. At roughly $5,800 and up, it costs more than twice the Christensen or DD5 and is overkill for shooters who will not exploit its precision and durability. Buy it when you want the validated, pattern-defining 7.62 gas gun and price is not the deciding factor.
