From tree stand hunting, spot and stalk hunting, competing at the range, target shooting or plinking with the kids, this mount will allow you to use a red dot on just about any Ruger Revolver.

Ultra slim design at only 1/8” keeps the red dot as low as possible on the gun. By design our mount incorporates both the rear sight screw and rear sight cross pin. The only mount on the market that uses the rear sight cross pin for ultimate strength. Similar to magnum rifles with cross bolts through the stock, the recoil force transferred is shared among both points, ensuring a single screw is not responsible for solo duty. The cross pin also prevents any twisting or rotating of the mount, ensuring any bumps along the trail have no impact on changing your zero.

But the features don’t stop there. Our mount comes with a special Shim Pack designed to tailor fit the mount to your specific gun. We are talking adjustments as small as 0.001″! This level of fit has previously only been seen in custom gunsmith one off pieces that would costs hundreds of dollars.

Even though all these models use the exact same rear sight, the tolerance difference between them is fairly significant. Especially when you consider these guns have been made during a 50 or 60+ year timeframe. Having a mount that can twist or rock from side to side is not a step in the right direction. Expecting one screw to control all lateral movement of the mount under recoil is irrational. The first step to mitigate that is using the rear sight cross pin and the next step is using our Shim Pack. Being able to custom tailor the part to your specific gun means you have the best fitting mount possible.

“Anything worth doing, is worth doing right.” – Hunter S Thompson

If you are inclined to drill and tap your gun for an additional screw but can’t bear the thought of ‘defacing’ your precious six gun, don’t worry, you’re not alone. That’s why we made provisions for a second screw tucked inside the rear sight pocket. Especially for those shooting full house loads and big bores with monster recoil. Maintaining the original outward appearance of the gun is important to us, especially if you wanted to go back to open sights or preserve resale value.

    Excellent design. Easy to install with a few tools. I like how low the mount is so the red dot feels more natural to the line of sight. Will be ordering more

  2. Tony Strange (Verified Buyer)

    Ruger Single Six – Haven’t had the chance to sight it in yet, but fit and finish is great, installation wasn’t bad at all. Can’t wait to get it to the range to dial it in.

    Quick shipping . Quality product .

  5. Fredrick Orme (Verified Buyer)

    The mount fit my Ruger Single 6 very well. My eyes are not as sharp as they used to be, so shooting with a red dot improved my shooting much more than I ever could have hoped for. Thank you for making such a helpful product

  6. Stanley B. (Verified Buyer)

    The Vortex Red Dot mount from Griffon Hill fit my Ruger Super Redhawk 480 perfectly. I highly recommend this mount for any Ruger pistol it is designed for.

  7. Gary M. (Verified Buyer)

    I had a gunsmith put it on for me. He said it took about five minutes. I zeroed it in and shot great groups with .357 hot loads. Stayed tight and on target.

  8. Kenneth O. (Verified Buyer)

    Overall I’m happy with this sight platform from Griffon Hill.

    A few obsevations:

    Use a drill press for the sight pin hole. Handheld drill can be difficult with broken bits and poor hole alignment.

    Lots of variation on mounting holes on sights. This uses 6-48 x 7/16 – not easy to find… will need to trim longer screws. Check your sight thru-holes for size!!!!!!!!!! Mine pictured is from Primary Arms and had to open the holes to accommodate the size 6 screws. Voided warranty….

    Haven’t shot it yet so jury is still out but expect it will perform well.

    Great mount. Much lower profile than my previous one.

  10. Derrek (Verified Buyer)

    Fit and finish were excellent.
    Installation instructions are step by step and easy to follow. Gunsmith installation is ALWAYS best, but you have the tools to do it IF you follow the instructions.
    This product made ALL the difference with my shorter barrel Ruger SBH for short range hunting.

  11. Kevin (Verified Buyer)

    Low profile makes for easy sight pickup. Still need to run heavy magnums, but so far I may order two more for other revolvers.

  12. Jay S. (Verified Buyer)

    Product is well machined, finished, and designed. Was also shipped from the west coast to the east coast in two days. I cannot express how great the included installation instructions were. They were clear, concise, and made every aspect of the install painless. The only thing that could possibly improve this mount kit would be the inclusion of the 1/16″ drill bit, that would make it 6 out of 5 stars. Tweezers are immensely helpful in dealing with the shims. Installed the mount and a Vortex Venom on my new model Blackhawk. Over a hundred rounds later at max load levels or hotter and everything is still tight and true. Glad I spent a little more money to an American owned small business and received a product that will outlast me. Thanks!

  13. WILLIAM FREAS (Verified Buyer)

    Easy to install on my new model Ruger Blackhawk 45 Colt. Very solid mounting system.

    Very well made Easy to install

  15. Chris H. (Verified Buyer)

    I could not be more pleased with my new Griffon Hill Ruger revolver red-dot mount, well made & easy to install, what’s not to like?

  16. Bruce Axtell (Verified Buyer)

    Fit very nice on the Security Six. Only .002 shims needed and were sure nice to have. Would like the ability to have a mount that uses the Shield type mount as I use Sig Romeo 0 sights a lot.

  17. Rod Stallings (Verified Buyer)

    Got this for my Ruger Super Redhawk in 10mm. Install was simple enough and I mounted a Viper Venom on it. Plan to take it to the range this week, to give it a go. Really like the setup. Perfect for this gun in my opinion.
