This is my second mount as the first one I had developed a horizontal crack in the centre of the upright. Given that I only shoot internationally, the pistol has not had thousands of rounds through it. I am, needless to say, disappointed in the product, which I purchased in 2015. Hopefully the new one will last a lot longer. However, the service from Double Alpha has been excellent and I shall continue to be a loyal customer.

I purchased the original double alpha c more scope mount with the adjustable thumb rest several years ago.it looks good and it does everything it is supposed to do. The mount has stayed solidly attached and maintains zero in spite of thousands of rounds of major power ammo.I have since purchased two more of the newer mounts with the adjustable thumb rest and have had no issues with either one.

I have now used this mount in my first match and I am sorry to say that i had to leave the match as a loser. The design of the thumb rest is a big mistake. The thumb rest is mounted with a screw from the inside on the vertical side . On the first target in a long course the thumb rest came loose and the screw prevented the slide to feed the next round . I had to help the slide after every shoot (32 shoot) . Afterwards I could see how the slide was scratched by the screw . Do I need to say that i had the worst time of all competitors. Yes , I had blue screw locking but it still came loose. Please redesign the thumb rest to be mounted from the outside on the vertical side.
