The LT104-30-VFZ is the best mount made for attaching high-power rifle scopes onto flattop-style rifles, period. The LT104 places the center-line of the optic 1.5" above the top of the rail for optimum cheek weld with a variety of flattop platform rifles. The cantilever positions the scope out front over the hand guard, eliminating the need to span from the receiver to the hand guard. The cantilever also allows the shooter to obtain proper eye relief. The popularity of the SPR series of mounts is partially due to the innovative backbone that connects the split vertical rings. This design provides a more robust platform for the optics, increases repeat-ability, and eliminates the need for time-consuming lapping. The rings are precision-machined with the tightest tolerances, and feature threaded steel inserts, built to withstand a lifetime of abuse. Like all LaRue Tactical mounts, it is precision-machined out of bar-stock aluminum and anodized. Assembly and adjustment only takes a few minutes, then off to the range.
