Knight's Armament SR-25 Tactical rifle *
Eugene Stoner, designer of the AR10 and AR15
(known to the World as an M16), working with US company Knight's Armament,
designed an SR-25 - a rebuilt in its original caliber AR10. Up to 60% of
parts of the SR-25 are interchangeable with the AR15/M16 - everything but
the receiver, the hammer, the barrel assembly and the carrier/bolt. Barrels
of the SR-25 is manufactured by Remington with its famous 5R (5 grooves,
rounded) rifling, with twist 1:1.25 (1 turn in 11.25" (286mm). The heavy
24" (609mm) barrel is free floating, so hand guards are attached to the
front of the receiver and do not touched the barrel. The light gas tube
does not affect accuracy. SR-25 is manufactured in 4 variants: Match rifle,
with 24" (609mm) barrel, Lightweight match rifle with 20" (508mm) barrel,
carbine with 16" (406mm) barrel, and Sporter, with 20" (508mm) not free
floated barrel. Match Rifle has no iron sights, and all models has a Picatinny
weaver rail system on the top of the receiver to accept different scope
mounts or M16A3 carrying handle with iron sights (front sight mounted on
the rail located on the forward end of the hand guard). This rifle designed
to shoot 1 minute-of-angle groups at 600 yards ( 150mm groups at 550 meters)
