rmr mount
In automotive design, an RMR, or rear mid-engine, rear-wheel-drive layout (now simply known as MR, or mid-engine, rear-wheel-drive layout), is one in which the rear wheels are driven by an engine placed just in front of them (i.e., the rear axle), behind the passenger compartment. In contrast to the rear-engined RR layout, the center of mass of the engine is in front of the rear axle. This layout is typically chosen for its low moment of inertia and relatively favorable weight distribution (the heaviest component is within the wheelbase, making the main component of its moment of inertia relatively low). The layout has a tendency toward being heavier in the rear than the front, which allows for best balance to be achieved under braking. However, since there is little weight over the front wheels, under acceleration, the front of the car is prone to lift and cause understeer. Most rear-engine layouts have historically been used in smaller vehicles, because the weight of the engine at the rear has an adverse effect on a larger car's handling, making it 'tail-heavy'. It is felt that the low polar inertia is crucial in selection of this layout. The mid-engined layout also uses up central space, making it impractical for any but two-seater sports cars. However, some microvans use this layout, with a small, low engine beneath the loading area. This makes it possible to move the driver right to the front of the vehicle, thus increasing the loading area at the expense of slightly reduced load depth.
In modern racing cars, RMR is the usual configuration and is usually synonymous with "mid-engine". Due to its weight distribution and resulting in favorable vehicle dynamics, this layout is heavily employed in open-wheel Formula racing cars (such as Formula One and IndyCar) as well as purpose-built sports racing cars. This configuration was also common in very small engined 1950s microcars, in which the engines did not take up much space. Because of successes in racing, the RMR platform has been popular for road-going sports cars despite the inherent challenges of design, maintenance and lack of cargo space. The similar mid-engine, four-wheel-drive layout gives many of the same advantages and is used when extra traction is desired, such as in some supercars and in the Group B rally cars.
A few months old, had it mounted on a TX22 22LR pistol. The circle dot (3moa dot, 65 moa ring) is just not for me in this application. Mounts to a standard RMR footprint. I couldn't get my phone to focus on the reticle, so the picture is just proving that it functions. The reticle is sharp and...
