LaRue Tactical SPR-S mount
Posted in AR, Optics on September 1st, 2006 by MilitarymoronSPR-S Mount – The SPR-S mount (LT158) is a one-piece base mount that’s basically the same as Larue’s SPR/M4 mount, but .080″ lower to place the centerline of 34mm rings 1.5″ above the rail when it is not necessary for the eyepiece of the optic to clear a rear backup iron sight. With 30mm rings, the scope is centered 1.41″ above the rail. It’s available with 34mm, 30mm and 1″ rings.
Overall length of the mount is 5.85″, including the cantilever extension in front. The rings are set forward so that the proper eye relief can be obtained when mounting a scope on an M4 or similar weapon. The base of the mount that grabs the rail is about 4″ long.
