T3 Felt Lined Top blocks

They are the exact same with as my Sinclair windage top so I use them with my Sinclair windage top and I made up some carbon fiber rails and they work perfectly so now I have a rodzilla type rest at a Sinclair windage which is perfect I use it on my competition base and I shoot F class I like it because it seems to be more precise than the coax joystick using dials and I extended my windage knob down to the base great product I would most definitely recommend to anyone
