The extra-wide, anodized aluminum base is ultra-steady on the rest with twin runners that track smoothly and help the rifle travel straight rearward under recoil. A simple, bolt-on way to give your rifle that rock-solid feel on the bench.The Sinclair Picatinny Rail Adapter lets you use the Sinclair Benchrest Forend Rail Adapter on a rifle with a Picatinny rail on the underside of the forearm.
