Manufactured in Vero Beach, Florida, the SR-25 is Knight's Armament Company's attempt at building the most accurate 7.62x51 mm NATO rifle possible. The rifle was developed with Eugene Stoner. The upper receiver is numbered to match the lower. It features a custom 30 inch long round handguard, which acts as the mounting face for the included silencer in the lot, surrounding the heavy barrel. Fitted with an A2 style pistol grip and fixed stock. A Harris SL bipod is mounted to the handguard via a 12 inch long mounting bracket on the bottom. Includes a bolt-on polymer cheek riser and Leupold Mark 4 8.5-25x50 mm LR/T scope with lens caps. Magazine absent.

Constructed from stainless steel, with a threaded front cap, internal expansion space, integral spanner wrench interface and threaded mount, along with a short section of .51 caliber bore at the end. Marked "JCB INC/PORTLAND OR." 13 1/4 inches overall, enclosed by the forearm when assembled.
