My primary match rifle sits in an MPA Comp chassis. I have a Sawtooth dovetail on the spigot and a RRS adapter on my bipod. For the most part, my bipod is clamped down to the spigot, but if I need to slide it to a different position for a barricade, the rail built into my chassis lets me do that quickly. I've also shot this rifle off my tripod with RRS leveling base numerous times and it's rock solid.
My Desert Tech and AIAX have a RRS plate that allows me to lock them both into my leveling base. Again, super stable and the only reason I bought a rail for my Desert Tech is because I suffer from GAS (Gear Acquisition Syndrome)
