SR-25

The SR-25 (Stoner Rifle-25) is a semi-automatic sniper rifle designed by Eugene Stoner and manufactured by Knight's Armament Company.

The SR-25 uses a rotating bolt and a direct impingement gas system. It is loosely based on Stoner's AR-10, rebuilt in its original 7.62×51mm NATO caliber. Up to 60% of parts of the SR-25 are interchangeable with the AR-15 and M16—everything but the upper and lower receivers, the hammer, the barrel assembly and the bolt carrier group. SR-25 barrels were originally manufactured by Remington Arms with its 5R (5 grooves, right twist) rifling, with twist 1:11.25 (1 complete turn in 11.25 inches or 286 millimetres). The heavy 24 in (610 mm) barrel is free-floating, so handguards are attached to the front of the receiver and do not touch the barrel.

First military purchase was spearheaded by the U.S. Navy in the early 1990s; the first operational deployment and use of the SR-25 sniper rifle was with U.S. Navy SEAL snipers supporting operations in Somalia in 1993.

Utah State Route 25

State Route 25 (SR-25), also part of the designated Fishlake Scenic Byway, is a state highway in the south central portion of the U.S. state of Utah. SR-25 runs from the junction of SR-24 near the town of Koosharem northeast to the west shore of Fish Lake. The highway runs for 9.995 miles (16.09 km).

Route description

Fishlake Scenic Byway is a route of 29.6 miles that traverses mainly through the Fishlake National Forest, Utah. The byway comprises SR-25 and County Roads FAS-2554 and FAS-3268, beginning at SR-24, and running to SR-72. The byway starts at an intersection with SR-24 and immediately turns north-northeast through mountainous terrain before descending into a basin where Fish Lake is located. The route continues northeast and passes the west shore of Fish Lake, Johnson Valley Reservoir, and ending at the junction of SR-72, just nine miles northeast of the township of Loa in southeast Utah.

History

The road from SR-24 at Plateau Junction east to Fish Lake was added to the state highway system in 1918, and numbered SR-25 by the state legislature in 1927. The west end was moved south to Fish Lake Junction in 1935 as a federal aid project, but the legislative description was not changed until 1953. The Fishlake Scenic Byway was designated on April 9, 1990 on SR-25 between SR-24 and Johnson Valley Reservoir. The Byway was extended on August, 1992 between Johnson Valley Reservoir and SR-72 to comprise the southern portion of the Gooseberry/Fremont Road Scenic Backway.

Alabama State Route 25

State Route 25 (SR-25) is a long and relatively rural State highway in the State of Alabama. From US-78 in Leeds northeast to its terminus at the State of Georgia line, SR-25 is the unsigned partner route of U.S. Highway 411. The southwestern terminus of State Route 25 is at its junction with State Route 5 near Pine Hill in Wilcox County.

Route description

For the first 50 miles (80 km) of its route, State Highway 25 travels in a north–south direction. This highway begins by traveling through rural areas of west-central Alabama, connecting numerous small towns in the Black Belt region of Alabama. From Greensboro to its terminus, the orientation of Highway 25 is in a general northeasterly/ southwesterly direction. As this highway begins its northeastward path, it passes through rural areas, villages, and small towns, skirting the southern area of the Birmingham Metropolitan Area in Shelby County.

The Double Oak Mountain area

State Highway 25 traverses one of the higher peaks in the Birmingham area, Double Oak Mountain, connecting the Coosa and Cahaba River valleys. The roadway was constructed between 1914 and 1921 with support from Buffalo Rock founder Sidney Word Lee, who owned a 3,000-acre camp in Calcis. There is also a railroad line that runs parallel with Highway 25 between Vincent and Leeds that tunnels though Double Oak Mountain below the highway.
